The first thing to do is turn the chair over, and look at all hardware. Get a screwdriver or wrench and tighten any loose ones. Even try to tighten the parts that don't appear loose. Over time, it is easy for screws and bolts to become loose, causing certain chair parts to rub together irregularly and create a squeaky noise. Apply a lubricating oil on all of the nuts, screws and bolts to help loosen the joints. Simply spray oil directly on the the chair mechanisms, and pat them dry. You can also spray oil on a soft cotton cloth, and rub the oil onto your problem areas to have more control over where the oil goes. Moisture in the air and air conditioners cause rust. Regularly applying oil prevents rust from occurring and building up. If the chair still squeaks after adding lubricant and tightening all bolts and screws, take them all out, and lubricate them with a light machine oil before putting them back in. To help you locate the area of the chair that is squeaking, have someone sit in it, and swivel from side to side. By applying weight to the chair to make it squeak, it will allow you to more easily locate the source of the noise to more accurately apply oil. Each time you apply more oil, ask your friend to swivel the chair so you can see if you put oil in the right spot. A chair may only squeak when you lean back, which is usually caused by too much tension where the spring's ends rub on the housing ends. To fix this, apply oil to the seat tension spring located inside the turn-knob housing. Simply loosen the seat tension turn-knob and remove the turn-knob to spray oil inside the housing. Desk chairs are often on wheels that may move a lot, so it is common for the axles in the wheels to need some silicone spray over time. Turn the chair over and spray the wheels. Then, flip the chair back over, and roll the chair to spread the silicone around the entire wheel. Collapsing into a chair will eventually cause it to squeak. Chairs go through a lot of wear and tear, so to keep your chair silent, be cautious when you sit down as to not speed up loosening joints.

Making sure you have a stable, healthy sperm count can increase your chances at getting your partner pregnant. Some studies indicate high temperatures around the scrotum can affect sperm production. Take measures to keep your groin cool to increase your chance at pregnancy. Avoid saunas and hot tubs. Try not to use warm electronics, like laptops, on your lap as this can affect sperm count. Try wearing loose-fitting underwear to increase airflow to your groin. You can also minimize the time you spend sitting, as this can heat up your scrotum. Like women, men can increase their fertility by eating a healthier plant-based diet. The antioxidants found in fruits and vegetables may help sperm stay healthy. Try to snack on fruits and veggies throughout the day. Have a salad before dinner and vegetable or fruit based side dishes. Try skipping dessert a few nights a week in favor of fruit for a sweet after dinner treat. Moderate physical activity may help increase sperm count. Try to incorporate some light walking, jogging, or biking into your daily routine. You could, for example, ride your bike to work instead of walking each day. You could also make a point of taking your dog for a long walk before bed each night. All of this can potentially increase your sperm count. Toxins found in pesticides and household products may have an effect on sperm count. If you work a job, like construction, that requires you to work with toxins, take preventative measures. Always wear protective clothing to prevent skin contact with chemicals. If you and your partner are struggling to conceive, consider seeing a fertility doctor to have a sperm count done. You will provide a semen sample, which will be medically tested to count the sperm. A sperm count lower than 15 million per milliliter of semen is considered low. Do not panic if your sperm count is low. There are many medical treatments, such as taking hormones and surgical options, that can correct a low sperm count. You will have to talk to your doctor to see which options are right for you given your medical history and current health.

Consult with someone who is an expert in Taekwondo to get the right weights for your height, weight, and experience. Put on the ankle weights after you are dressed in the morning and wear them constantly throughout the day, even when driving, or working if you can. If they become uncomfortable to the point you can't bear it anymore, take them off for a few minutes then put them back on. This will work out your leg muscles and make your legs stronger. Make sure you focus on accuracy of your kick before proceeding to improving speed.

One-sentence summary --
Buy ankle weights from a sporting goods store or department store. Put on a thick pair of socks. Don't practice kicking with weights on; you'll risk serious knee injury if you do! While wearing the weights, practice different leg exercises, such as lateral leg raises, lunges, squats. Practice your kicks as per usual, but without weights! Watch to see that after a few weeks you'll be so much faster at kicking when not wearing your weights that you'll be able to wait on someone to start to kick you, and you'll be able to kick them first.
