The man basically is an animal who is lazy and wants to rest until he can no longer afford to. There are things he has to do absolutely like going to loo, eating, earn to eat and live comfortably to survive. He likes to lie down, sleep, make love, sleep again. But ultimately to survive, he has to move and do work may be grumbling. In the advanced years, the knowledge somehow dawns upon him that without doing exercises, walking he cannot remain fit, then he starts all sorts of exercises and walks daily because he does not want to die. He is selfish to the core. After making love, he likes to fall in deep slumber, detached from the partner whom he was smooching, hugging and kissing just a while ago.
