A dream life that Bill Gates has

Always enjoy watching any TV coverage about Bill Gate as in tonight's PBS Charles Rose program. He has made his personal mission and used his fortune to try to eradicate top five diseases in his lifetime; constantly and diligently read books in various disciplines; devise thermos to people in Africa that can keep vaccines cool for 50 days without any electricity; have brainchild to make toilet without the need of sewage system in Africa to prevent the spreading of epidemics. He has never been a bon vivant but is so happy to spend $30M USD to buy the original manuscript from da Vinci for his ingenious engineering works. What a dream life that he has!
