You would not blame them for trying, if you had as much money, resources and influence as they do, you may also fancy the idea of immortality. I wish that these billionaires can have another look at what immortality really means. Apart from what we know that it means never dying, someone can also be immortalized by their creations, innovations and brilliant life changing ideas, and some of these billionaires have already done that. If you look at Elon Musk for instance, due to his creations, he will be talked about for a very long time even after his death, just like we still hear the names of some other great men who have lived in the past.
