There has been and probably always will be very little interest in really old Tropicans, until somebody writes a scenario which requires or rewards having them. Since at age 65, Tropicans retire and become a burden on the economy, most players are glad to see them die. Some even hurry them along.
Your data is almost the first about the oldest. It is certainly the first which involves intent to prolong life. I take it that when you speak of a Hospital, you mean one which is set to the geriatric option. I don't know of any reason condominiums and roads would have any effect on the length of life.
So I think you have established the maximum life expectancy. I suspect it is not a deliberate cut-off in the program, but rather the simple result of the random selection for death routine.
Thanks for the information.
Have seen post of people having people over 100 years old, hope to see 1
I fear that such posts are from so-called players who are running their mouths to increase their post counts or attract attention to themselves.

Oh! No, there is no cheat to bring a Tropican back to life.
