It doesn't sound like a reality based story to me. I mean, who has the energy to go all out 2 times each day. And when does he sleep? Discount eating, bathroom and commuting and there is not much time left.

Also after working 40 hour weeks for some time I think you really need a weekend to get some stuff done at home and all the personal correspondence. Also you really should relax some time, otherwise you burn out faster then a tea candle.
