I guess my thinking about this conundrum is that anything regarding "happiness" or "health" - in my opinion - comes down to an issue of sustainability. Sure, I can be happy on the day I get some good news, but will I be happy on the day where I have to sit through frustrating traffic and getting cut off by every asshole leasing a Land Rover and going to work about the same time as me? Hm, I mean, I can try, but it's not like I can reach into the glove box, grab a carrot stick, chomp away and suddenly feel like I've just gotten out of having a nice swim off the coast of Cabo San Lucas.
As a species I do think studies considering what makes us "happy" and "healthy" and how we can treat "depression" or other "disabilities" of various degrees are worthwhile. But, when I see goals like this:
>Other studies will aim to establish best practices for corporate wellness programs by testing their efficacy.
I just laugh, because we already know the combination of how to make people happier and healthier (don't over work them, provide time for exercise, provide guidance and resources to eat appropriate diet as fresh as feasable) but there's not a "study" yet that has convinced the working US corporate culture to change. Maybe Harvard can finally do it. Yay.
