If you exercise for an hour, at least half of your time should be spent doing cardiovascular exercise. true or false?

The answer to your question is True

i think it's the first one because doctors aren't the ones who get rid of the old needles. most of them time it's not even doctors who give you shots, it's nurses.

it hurts at first because " the cherry is broken" which is a thin layer of skin that breaks so the first time girls have sex it hurts and it bleeds but after the first time it does hurt again because the skin that ia torn does not break again/ grow back.
