Hello,
Answer to question 1:
It is very useful to increase your flexibility because it helps your body to move better and stay active. Also you will get less pain from moving a lot if you body stays in shape.
Answer to question 2: Increased flexibility in sports is relay important. It helps the person to stay active and work his/her body. Ex. If your playing foot ball, you know all the plays in the book. Your really good and you work out. Now you stop playing for 5 years. Mostly if you trying foot ball again you will not play the same from 5 years ago.
So Flexibility is very important in everyone daily life to stay healthy and strong.
Hope this helps.
A food handler should stop working until it has no more signs of infection. Or wear long gloves that go up their arms. I hope this is what you want.
It means you are dehydrated
I think that it is talking about how stress comes from the way we think and act because there are negative outcomes in some situations. And the stress could also help because it could make you think back when something like the situation you are in now and see how you can solve it. With the courage you have for a response. Also, if you see someone else with the same problem that deals with stress you can relate with that person b/c of stress that you get. Then, you and that person create a resilience.
Hope this help
