Longevity is Coming

I think humans could eventually live 300 years or more. That would change the world in ways we’re only beginning to consider.

Medicine may be able to keep the body at a biological age of 25 to 35. At that point, people would rarely die from illness; accidents would become the main risk. We’re seeing this in animal studies, from mice to dogs and primates. I don’t think there’s a limit.

Someone who is 200 years old with the biology of a 35-year-old could still be working. That could solve the falling birth rates and shrinking workforces countries worry about. Scientists could take on projects that span a century. People would have time to reach goals they never had the chance to pursue before.

Health care would become injury care. Most of the conditions people see a doctor for today could disappear. Governments would want their citizens on these treatments if keeping people young costs less than treating them in old age. The drugs are expensive now, but prices will come down. The first people to benefit will be those who know to ask their doctors.

If we maintain our immune systems, we can live long, healthy lives.

Longevity is coming!
