>I get paid to think things and can reasonably expect to live essentially disease free until my 70's. Achieving 90 in relatively good health and vitality doesn't seem out of the question. No, you'll probably start suffering from diseases of affluence well below that. Sooner or later, heart disease, lung disease, diabetes, cancer, and pals crop up among basically everyone who doesn't carefully optimize their lifestyle to maximize health. In fact, the same principle applies to most of the rest of your lifestyle: it all seems very nice because you're discounting the incredibly careful and difficult-to-duplicate optimization of everything from personal habits to major life choices. Your entire life (our entire lives, really: it's me too) is essentially golden handcuffs. This is a major step up from handcuffs made of rusty saw-blades that cut and give you tetanus whenever you move, but you're still actually handcuffed.
