A very good summary of much of the field, but there are many practical matters to consider. Anti-ageing is not going to be primarily a technological matter. To see why this is the case, let’s consider the typical US citizen of today. There’s an 85% probability s/he will be overweight, obese, or morbidly obese. This is because our typical citizen eats junk and doesn’t exercise. Their health is consequently atrocious. Using clever biotech to extend the life of the average citizen is akin to trying to keep open a bridge that’s riddled with rust.

This leads us to a second point, which is longevity in and of itself is worthless without good health. I’m all for encouraging people to extend their healthspan (the years of life in which people are healthy) but the hard fact is that very few people are interested in eating things that are good for them and exercising regularly. If that’s the case today, we can only imagine how much more difficult things would be if people had the option to take medications that promised to extend their lives by a significant percentage. “I’ll start running in a few years from now” and “I’ll get to it later” would become even more prevalent as excuses.

Personally I find the science behind longevity quite fascinating, but I’m unconvinced that we humans are well placed to make good use of what science is uncovering. Most of us just seem to want to sit staring at a screen while stuffing McSlop down our throats. And that’s no basis for living an adequate life, extended or otherwise.
