I'm (ahem) over 50 and I just timed 120 second in my head and came out to 2 minutes 9 seconds. I cheat though, since I count to the beat of ZZ Top songs. These days the CPR people use Staying Alive, which feels faster to me, so I tried that, and got 2:10.

Then I tried it without counting -- 2:12. That can't be considered fair, since I already read the part about how over 50s mark time faster, so I could have subconsciously slowed my roll. Still, it's fascinating to me that I'm 3 in a row within 3 seconds.
