I enjoyed reading a post by Trent at The Simple Dollar on his switch to a plant-based diet for health reasons. I especially appreciated this statement:
As I thought about the options, I asked myself whether it was really important to me to eat certain foods. “How many years of good health is it worth for me to give up food X?” I realized that, when I thought of it in that context and in relation to watching my kids grow up and do whatever life has in store for them, I didn’t really have to add too much good health to my life to make it worth some significant dietary changes.
I couldn't agree more. This level of thought is exactly what I think many of us need. We need to always consider how our current actions are shaping our future. If we are doing something everyday, we must think to ourselves, how does doing this everyday add up at the end of a year, at the end of ten years? If it's exercise, we'll see some major benefits, but if our everyday activity is smoking, ignoring our children, eating a fast-food burger or driving recklessly, we might reconsider our current actions or have serious future consequences.
Back to food, here's some resources:
