I've almost finished reading John Robbins' "Healthy at 100"

It is a refreshing read - which gives a totally different view on health: the more sick you are, the more exercise you need to do, along with intake of good nutritious food (good food is not necessarily healthy, hehe)

Two things that I can make them sustain, hopefully:
1) Cook more raw food, instead of processed food
2) do more exercise, and I've opted yoga after work instead of running in the morning

Let's see how it goes.
