What is your "realistic" lifespan settings?

1 day =1 month in my game. I got a mod that makes pregnancy last 9 days. However I think 3 days season is a bit too short, so seasons last 6 days, and a full year of all 4 seasons= 2 sims year. Babies are babies for 12 days, then they are 1. Toddler for 48, making them 5. Children are kinda boring in the sims 3 as they can hardly do anything compared to The Sims 2, so they age up to teens when they are 11, a total of 72 days. And then teens for 84 days, at wich point they are 18. Then they are YA until age 40. I was thinking adult until 67(retirement age here), and elder roughly until 84. But people are more agile now then before, so I added a few years ekstra as adults and cut down on the elder stage instead. In Total they live around 1000 days unless something else kills them before old age.
