To be realistic, lots of times a simulation would have to capture the feeling of having 6x to 7x the fairly mature adult experience compared to the same person at 30 years old.

And the accompanying multiple of confidence and proven ability to go with it.

Plus a much bigger multiple of both, compared to your younger self at under 30.

You really can do most of the same things after 60, and with maturity it's easy to accept how the big difference is that you wont be doing them as many additional decades into the future.
