I think it's fairly common knowledge that it's best to learn a new language when you're young but apparently the peak age is 8. Most of us have probably passed that, but hopefully we still have a lot of peaks yet to come!
Here are some of the most noteable:
Creativity, Strength, and Having the Most Friends - 25
Running a Marathon - 28
Marrying and Not Divorcing, and Sex - 28 to 32
Losing Interest in Popular Music - 33
General Happiness - 38
Salary - 48
Being a Best Selling Author - 50
Fortunately for me, since I turn 27 this summer I still have a lot of peaks to come, but I am bummed about the ones I've already hit. Now I know to enjoy these other peaks as they happen! Check out the rest below!
Haha, peaks...get it? ^^
