Why is Elon Musk spending his time on Twitter and not on the Mars mission?

Then, of course, there is his own personal story – the great 51-year-old billionaire with 10 children, ranging in age from 1 to 18. His first son died when he was just 10 weeks old. Musk, who was born in South Africa, described living with Asperger’s Syndrome, a type of autism, and stated that his main goal in life was to colonize Mars.
