Young Adult and Adult agespan adjustments

This Mod only adjusts the ages for the Young Adult and Ault lifestages, since I believed them too short in comparison to the durations of all the lifestages preceding it. All my parents kept dying before their children were even grown... Young Adult went from 18 to 25 days, while Adult went from 20 to also 25 days.I also changed the age Elders are considered to be at the start of their lifestage (from 65 to 68 in human years) and the same for adults (from 40 to 43) wich lines up with their adjusted agespans.Hope you'll enjoy!
