Calorie Restriction and Increased Lifespan

Here's a pretty interesting video about increasing your lifespan. More and more, we're hearing about how eating fewer calories can extend our lives.

Well, yeah!

I mean, what is "calorie restriction" anyway? It means we eat too much but we're only eating based on amounts that we've come up with. So maybe it's just that our science has been a little off. Then there's that whole other issue of eating WAY too much and lying about it. We produce about 3,900 calories of food a day. The average person claims to be taking in 2,000 calories per day. That's a lot of missing food to be accounted for. Can you image how we would change to dynaimic of the planet if we only needed to produce 2,000 calories a day?
