Thanks but no thanks. Living to 150 means working until 140; 130 at the earliest unless a fortune could be made to support the person before that. Social Security and other pensions would not begin until 135.
Besides, the way the left and the young are ruining everything in their path, who really wants to see the world we knew be destroyed from within?
If you have not figured out how to become of independent means after 50 years of working, you have not bothered to read the numerous books on the subject.
Saving just 10% of your income for 50 years at 7% annual interest after inflation (index fund of the stock market for the last 80 years) gives you 45.6 times your annual income in investments, or 3.2 times your annual income forever (at 7% return).
At a very modest 4% annual interest after inflation, you get 16.0 times your annual income, or .64 times your annual income forever (at 4% return).
