I got an email about this guy. I wonder if he's human.
He's a Navy elite SEAL, and runs purely for charity purposes to raise funds for needy families
Truly inspirational.
The reason I posted here though, he claims he gets 3 hours of sleep per night, and spends almost his entire day on strenous activities
Check his site, especially the 'daily workout': http://the100mileman.com/davidgoggins/
Makes us look like a bunch of babies, doesn't it
