Nowadays more and more people join healthy lifestyle. And one of the main factors, that influence(S) people's decisions in this question, is education.

Also there are a lot of gyms with varied trainers, so everybody can keep themselves fit. And the last but not the least thing, about which I would like to say, is the level of our medicine. Current technology allow(S) us to treat almost any illness, what(WHICH) helps us to be healthier and live longer.
