Chaosium produced Ringworld back in the day a Sci Fi setting based on the novels of Larry Niven. If memory serves they did a good job of translating the Tech from the novels into the game. In the setting Humans had achieved extreme life extension with older persons able to acrue vast knowledge and experience over the centuries with no physical detriment. So older charecters were vastly more competant (more skill points) than younger charecters.
