Obesity is the second leading cause of preventable death, behind tobacco.

You know why this is? Because we solved the equations for food supply in the first world ages ago. The US is a MASSIVE net exporter of food, even while we enjoy more and larger portions than any people at history.

We've already largely automated away from physique as an economically relevant factor- athleticism is less relevant than at any point in history.

We've cured or found treatments for almost everything that ever caused people to die young- the flu is a joke compared to what influenza meant a century ago, while dozens of our old plagues are extinct, or nearly so. How many of your family have died of polio lately?

The list of things that can kill you is getting a lot shorter. Since everybody dies eventually, this means that the remaining causes are going to take up a larger share. And obesity is the big winner because it's also getting more common- because we're not on the verge of starving to death like a lot of our ancestors.

Life is good. We're literally dying because we have it too easy. It's almost funny, from a historical/philosophical perspective.
