Disregarding Neurogenesis, this guy is attempting all-at-once to,

1. Stop smoking, that is from almost chain smoking to none.

2. Start running 4km a day - I've done this, takes incredible amount of effort.

3. Lift etc. every evening - Not as hard as 2, but close.

4. Start meditating - if you do the proper way, incredibly hard.

5. Avoid junk food - difficulty depends, but sounds like he does consume pizza or Ben&Jerry’s daily.

I'd love to seem him succeeding in the 'coming weeks', but he won't. It'll take years at least.

He'll get linked though.
