PROBLEM: Article: At night, bats fly through the air, catching hundreds of insects and other small animals. But during the day, they hardly move at all. Instead, bats pass the time hanging upside down from a secret spot. There are a couple of reasons why bats rest this way. First of all, it puts them in a position for takeoff. Unlike birds, bats can't fly into the air from the ground. Their wings don't produce enough lift to take off from a dead stop, and their hind legs are so small and underdeveloped that they can't run to build up the necessary takeoff speed. Instead, they use their front claws to climb to a high spot, and then fall into flight. During the hours when most enemies are active, bats gather where few animals would think to look and most can't reach. This allows them to disappear from the world until night comes again. There's also little competition for these resting spots, as other flying animals don't have the ability to hang upside down. Bats have a unique physiological adaptation that lets them hang around this way without using any energy. For you to hold your fist around an object tight, you contract several muscles in your arm, which are connected to your fingers by tendons ;as one muscle contracts, it pulls a tendon, which pulls one of your fingers closed. A bat's talons close in the same way, except that their tendons are connected only to the upper body, not to a muscle. To hang upside down, a bat pulls its claws open with other muscles. To get the talons to take hold of the surface, the bat simply lets its body relax. The weight of the upper body pulls down on the tendons connected to the talons, causing them to hold tight. Therefore, the bat doesn't have to do anything to hang upside down.

PROBLEM: Article: Giving bad news is a difficult ball game. To help you get through an already difficult situation, try these tips when you have to tell someone bad news. Think about your audience. People respond differently to bad news. Think about who you're talking to and how best to pass on unpleasant information to that person. Consider the news. Are you the best person to give this news? If not, then you should consider letting others do it. Remember, however, that if you're talking to someone about your relationship, there is no other choice. It is something you yourself have to face. Look for an appropriate moment to break the news. You don't tell the bride her grandfather died right before she walks down the passage. Wait until the time is right and you are at a private place where you won't be interrupted. Find a chair. No one should be standing when receiving bad news. Go straightforward. Give bad news the same way you take off a bandage: QUICKLY. Say that you have bad news and then tell it. Don't leave the receiver twisting in the wind. Let it sink in. Many people mentally shut down when hearing bad news. There's no reason to keep talking if someone can't hear you any more. Be ready for anything. Your audience may do nothing or may instead scream and throw things when you give unwelcome news. You just never know. If things get out of hand, you may need to temporarily excuse yourself or seek the help of friends or s. Offer your help. Let people know you are there for them. If you're breaking up with someone, however, you should consider skipping this step, because the last thing she'll want is your help.
