"Do you want a guy like this at your company? This is absolutely poisonous from a culture perspective. Not only does the guy not want to work hard, he equates working hard with "losing your health". Somehow I missed seeing that Levchin, Thiel, Brin, Zuckerberg, Pyncus, and every early Googler and Facebooker were in wheelchairs for carpal tunnel syndrome. It's really not that hard to work hard and work out at the same time (even the dreaded brogrammers manage it)."

I think you miss a point that working hard doesn't equate getting things done. I saw a lot of people working hard (in number of hours) and net gain from their effort is zero or less.You should be focused what kind of results you would expect to have from one day's work or pay me proportionally to my output which can be 10x more than that of hard working guy. I am fine with that. Putting long hours just to fit in culture is not smart thing in the long run. Note one more thing , 'old farts' have more to lose if they do shitty job than some no family/mortgage guy in early 20s.
