Year of Class Reunion (or Midlife Crisis)?

I missed my college class reunion earlier this year. Last week my mom told me my elementary school classmates were also organizing a class reunion. Since I was not able to attend, my mom gave them my email address. Lo and Behold, I got tons of emails from my classmates today. Gee, is 2011 the year of the midlife crisis for everybody? How come I have so many class reunions?
