That is very obvious from the pictures even myself they I have not known him before the recent controversy concerning ETH knows from the picture that he is not feeling too well its so unfortunate that the brightest mind are the ones that get to witness failing health and hoping he will recover because ETH to me is a legacy that would stay even beyond majority that saw its emergence in this crypto world.
Well, he is rather smart, sure, but it doesn't mean he can maintain the support of ethereum and keep it being competitive. All in all, he's still a very young man who's probably more into enjoying life than working. As for his health, there's nothing on the Internet about it, so I guess it's just the way he looks and probably drugs. Anyway, eth is doing rather fine, so I guess we shouldn't worry on this matter now.
