Elon Musk is an inventor and a workaholic of epic proportions

The problem is that he is now 47 years of age and you cannot keep up the pace he has lived at forever. For example, I had to slow down at age 50 because I wound up with a heart virus. So, health problems can start to be a problem when you pretend you are still 25 and almost 50. So, I'm thinking that he is just pushing himself too hard for the present age he is and something's got to give. And trying to make decisions without enough sleep or rest is also not going to work at 47 either no matter who you are because the decisions you make won't be worth anything.
