Q: A skier takes a jump during sunny winter weather at the Swiss mountain area of Hoch-Ybrig, south of Zurich, February 23, 2011. REUTERS/Arnd Wiegmann Lisa Wheeler, a New York-based fitness instructor, believes it's never too late to get in shape to make skiing more enjoyable and safe. But don't overdo it. "Do some basic strength training for the legs, core and arms," said Wheeler, fitness program director for DailyBurn, an online workout site. "But if you haven't done anything, dial it back a little." Wheeler recommends lunges to strengthen the quadriceps, the long muscles in the front of the thigh. "Lunges are quad-dominant and skiing is very quad dominant because your knees are bent and you're going downhill," she said. "And lunges also work the hamstrings and glutes," she explained, referring to the large muscles that form the buttocks. Wheeler thinks the novice can forgo jumping or hopping lunges and concentrate instead on matrix lunges, basically stepping to and pushing off different directions across the range of motion. "For the last-minute person I recommend taking it easy," she said. Wheeler said people think of skiing as going in one direction, downhill, and neglect to prepare their hips and core for the considerable demands of the activity. "If you analyze skiing there's a lot of rotation and lateral movement of the hips," she said. "I would do some core exercises, such as planks, and rotational movements with the medicine ball," she said. "Because going down the slopes your body is turning, your hips are turning." Jessica Matthews of the American Council on Exercises suggests exercises that mimic the activity of skiing, which along with cardiovascular fitness and muscle strength, demands a measure of speed and agility. "I'm a huge fan of cone drills," she said. "I just picked up a set for the house." Sold in sporting goods stores, cones are smaller and lighter than traffic cones. Matthews, an exercise physiologist, thinks they are ideal for setting up a circuit to train for the movements of weaving down a mountain. "You can work on developing lower body strength, lateral movements, do cone jumps and practice proper landing," she said. Squats and lunges build lower body strength but for those challenged by a full squat, Matthews suggests the wall sit, which is essentially placing the back against the wall with knees bent. Ideally, she said, you want to begin a pre-ski routine at least six weeks prior to hitting the slopes. "That's a good time from physiological standpoint," she said. Another crucial element to skiing is the ability to react quickly. "Downhill is not straight downhill," said Matthews. "You have to dodge people. You've got to be able to make quick changes, you might have to counter a fall, so it's important to make sure your hips, legs, shoulders, spine are all ready to go." Wheeler said.

Q: Siteman Cancer Center at Barnes-Jewish Hospital plans to open a second proton therapy center in 2020, and Mercy Hospital St. Louis expects to open its own proton center two years later, The St. Louis Post-Dispatch reported . Proton therapy zap cancerous cells with precise beams of radiation while sparing surrounding tissue. Unlike traditional X-rays, the proton beams stop at the tumor instead of traveling through the body. The new $32 million proton system planned at Barnes-Jewish Hospital will provide "pencil-beam" precision to target tumors, said Dr. Jeffrey Bradley, director of Siteman's S. Lee Kling Proton Therapy Center. It will be built next to a $20 million machine, which opened in late 2013, that uses magnets to scatter proton beams across a tumor. Siteman has treated about 800 patients with the proton therapy, close to its projections of 200 patients a year. The first proton centers built in the 1990s were known for their football-field size and up to $200 million price tag. To offset the costs, the centers marketed heavily to men with prostate cancer, despite a lack of evidence that patients have better outcomes or fewer side effects compared to cheaper treatment alternatives. In 2013, Washington University was the first to open a smaller, less-expensive proton system with one treatment room. "That's very different from other centers that went all in, borrowed money, and put in four-room centers," Bradley said. "The one room at a time idea is a very viable idea." Bradley and other radiation oncologists say a major hurdle is insurance companies' reluctance to cover proton therapy. That can cost 50 percent to 75 percent more than traditional radiation, according to industry groups. "Where the insurers like to say that proton therapy is not beneficial is often because they do not perform an adequate review of the evidence," said Scott Warwick, executive director of the National Association for Proton Therapy. "We have notified the payers that they have often either misinterpreted data, reviewed older evidence or omitted key evidence in development of their coverage policies." ___ Information from: St. Louis Post-Dispatch, http://www.stltoday.com

Q: As tensions rose in September 2017 in response to football players' protesting police brutality and inequality by kneeling during the U.S. national anthem, astronaut and former football player Leland Melvin jumped into the fray with a lengthy open letter to president Donald Trump. During a September speech in Alabama, Trump hadcalled for a boycott of the National Football League (NFL), saying: Wouldn't you love one of the NFL owners when someone disrespects our flag, 'get that son of a bitch off the field right now' . . . If you see it, leave the stadium, I guarantee things will stop. Trump's words heightened emotions on both sides of the issue, but for athletes and team owners, it seemed to heighten solidarity and even spread the protest to as quarterback Tom Brady and National Basketball Association players Steph Curry and Lebron Jamesspoke out against Trump. Amidst all this, a lengthy open letter to the President purportedly penned by astronaut and former NFL Player Leland Melvin came to light: To Donald Trump I believe in the Declaration of Independence and the Constitution of this country even though at the time they were drafted, their tenets of life, liberty justice for all and eventual freedom of speech, religion, assembly, press and petition amendment ratified in Dec 1791, only applied to a select group of people and not ones that looked like me. Donald Trump I listened to your Alabama rally rant and could not believe how easily you say what you say. We have become numb to your outlandish acts, tweets and recent retweet of you knocking down Hillary Clinton with a golf ball that you hit. Donald Trump your boorish and disgusting actions are not funny. They actually promote violence against women especially when your followers act out what you say. I used to walk the grounds of UVA in Charlottesville, VA as a graduate student only to watch in horror as those same grounds became a battlefield being trod by Nazi and anti-Semitic worshippers armed with assault style weapons ready to fight to make America White again. (their words). You actually said there were nice people on both sides. People armed and ready to kill other Americans for the purpose of eradicating Blacks, Jews, Hispanics, Mexicans, Asians, Latinas and even the first real Americans, Native Americans to make America Great Again were "nice people"? Verses what you say in condemnation of an unarmed black man peacefully protesting by exercising his constitutional First Amendment rights by silently taking a knee is appalling, unnerving and reprehensible. You called Colin Kaepernick "a son-of-a-bitch." And said he should be fired. You are basically calling his white mother a bitch. The strong contrast in language for a black man and a Nazi is very telling. Do you have any sense of decency or shame in what you say to the American people that are part of your duty to serve respectfully with dignity, presidentially? The National Anthem that we listen too has been edited to try not to offend because when Francis Scott Key penned the song he watched freed slaves fighting for the British and wrote this stanza: "And where is that band who so vauntingly swore, That the havoc of war and the battle's confusion A home and a Country should leave us no more? Their blood has wash'd out their foul footstep's pollution. No refuge could save the hireling and slave From the terror of flight or the gloom of the grave, And the star-spangled banner in triumph doth wave O'er the land of the free and the home of the brave." I guess if I were a slave back then I probably would have done anything to obtain freedom from my American oppressors who were whipping, killing, raping, dismembering, hanging or releasing the dogs on people like me all under our Constitution. In 1814 former slaves fought with the British for their freedom from their American enslavers and Key witnessed a battle from a ship off the Maryland shore at Fort McHenry which inspired him to write what became our National Anthem. I served my country not in the military but as 1 of 362 American Astronauts that have explored the universe to help advance our civilization. Not just Americans but all humans. I also was briefly in the NFL and stood for the National Anthem with my hand over my heart. What makes us great is our differences and respecting that we are all created equally even if not always treated that way. Looking back at our planet from space really helps one get a bigger perspective on how petty and divisive we can be. Donald Trump maybe you should ask your good friend Mr. Putin to give you a ride on a Soyuz rocket to our International Space Station and see what it's like to work together with people we used to fight against, where your life depends on it. See the world and get a greater sense of what it means to be part of the human race, we call it the Orbital Perspective. Donald Trump please know that you are supposed to be a unifier and a compassionate and empathetic leader. If you can't do the job then please step down and let someone else try. I pray that you do the right thing. May God bless you. Sincerely, Leland Melvin Former Astronaut and NFL Player It's unclear why this particular response was met with skepticism, but several readers wrote in to ask us if the letter was authentic. It's possible that many were unfamiliar with Melvin. Some may have also questioned the authenticity of the national anthem stanza mentioned by the former NFL Player (it is indeed part of the song). The length of Melvin's post, which was significantly longer than most of the other responses that circulated on social media, may have also raised some doubts. However, this open letter was truly written by Leland Melvin. It was originally posted to his Facebook page on 23 September 2017: To @realDonaldTrump I believe in the Declaration of Independence and the Constitution of this country even https://t.co/FezF6vqZuO pic.twitter.com/VUGdZa7lL0 Leland Melvin (@Astro_Flow) September 23, 2017
