Pfizer sponsored a survey from AARP that found the average age for different milestones in people's lives.  Here's what they found out:       

You have your FIRST KISS at age 15. 

You're financially independent from your parents at 22. 

You have the BEST SUMMER OF YOUR LIFE when you're 24.

You start reminding yourself of your parents at age 32.

You begin FEELING YOUR AGE at 38.

The age when you should stop having kids is 41.

You should RETIRE at age 64.

And you should expect to LIVE until you're 84.
