It is like that old joke about taking cold shower every morning for 100 years.

You know that cheesecake is not very good for you, but what is the alternative? You eat that celery stalk but where does it get you?

The best case scenario - raw food eating Jack Lalanne dead at 96. His death heavily shook my belief in healthy eating.

Worst case scenario his brother Norman Lalanne and everyones favorite Jeanne Clement neither of which were much for exercise and Jeanne indulged in smokes and chocolate.

Sure those are anecdotes but we do not have any healthy 150 year olds.

Obesity kills, but non-obesity kills just slightly slower. Slower I define as 10-70 years slower.

We need meaningful progress with other aspects of aging (telomere shortenings, cancers etc) before we can tackle obesity.
