I'm posting one puzzle, riddle, math, or statistical problem a day. Try to answer each one and post your answers in the comments section. I'll post the answer the next day. Even if you have the same answer as someone else, feel free to put up your answer, too!

Weak, Sweaty and Cold
I make you weak at the worst of all times.
I keep you safe, I keep you fine.
I make your hands sweat, and your heart grow cold.
I visit the weak, but not the bold.
What am I?
