During a sandbox game running 100 years to observe the forestry replacement mechanics I noticed really old people.
A 126 year old wench providing services to a 130+ something Henry Morgan.
Death through natural causes/old age could add a new dimension - even on the long 30 year games. Would have been more realistic to have a random maximum age calculated for each individual and kept hidden. A formula something like 50 + 5D10. Wealthy captive investments at risk, key persons like Captains are lost....
I notice a posting on Tropico1 that showed people died off. 101 age being the highest age posted in that thread. Suggests to me that the original had an age related mechanic - wonder why it was removed for T2
