Well Hunter S. Thompson was just on another level. Here's a clip of Rogan detailing his daily routine. I'm super surprised he lived as long as he did!
Bourdain had turned his life around, famously by quitting drugs around the Kitchen Confidential years, but recently Rogan had gotten him addicted to BJJ. He got ripped! He had a six pack and even was able to go off the statins he had been taking. I don't usually see people with that kind of dedication to a healthy discipline commit suicide, so I was a bit surprised too.
When I watch No Reservations, and Parts Unkown, the show is so intimate I start to think I know the person, but I guess you never truly know what's going on with someone when you're getting a filtered view.
But Rogan was surprised by it, and he knew him pretty well...

Anyways, I'm sure with your engineering skills you'll do just fine with whatever future endeavor you choose!
