Research is great -- I'm all for that -- but I'm less certain about actually turning this into a product just yet.<p>As an analogy, it is like a weekend cyclist spending $10,000 on a high end bike to save a pound or two off their bike, meanwhile they are 30 pounds overweight. It would be better to lose that weight (for cycling performance and for many better reasons) before trying to buy cycling performance at $10,000/lb.<p>Getting back to the point, people imagine it would be great to live 500 years, perhaps longer. Ask yourself: are you maximizing your current life? If you are currently unhappy, bored, sick, lonely, feeling like you are trapped in a certain lifestyle, why would you want an extra 400 years of that?
