Well this strikes pretty directly at the heart of the whole longevity argument. There was an article on HN the other day about Bryan Johnson and how he was spending millions a year, eating exactly 1977 vegan calories per day, taking a dozen pills every day, doing 1 hour of high intensity training, and as a result some tests showed that he was scoring like an 18 year old.

It's all a bit... self-defeating? You're going to live forever spending your entire life.... trying to live forever? Living a long life isn't necessarily living a good life, and wasting the time you have in order to get more time.... maybe stop doing that and just get on with doing the stuff that you want to do given the time.

Having said that, on your analogy, it's a great business selling $10,000 bikes to rich idiots...
