Elon Musk repeatedly breaks down in interview as he admits taking pills to sleep and explains bizarre Tesla tweet

Elon Musk repeatedly broke down in an interview in which he attempted to explain some of his recent strange behaviour. The Tesla boss has admitted to taking pills to sleep and that he has had a difficult year, alternating between laughter and crying as he did. And he revealed that the stress of the year appears to be undermining his physical health. "It's not been great, actually. I've had friends come by who are really concerned," he said. The I.F.O. is fuelled by eight electric engines, which is able to push the flying object to an estimated top speed of about 120mph.
