I started around age 12, am 35 now.. so that's 23 years.. sometimes in there I'd only do it every few weeks, sometimes many times a day. So I'll average it to sometimes twice a month, sometimes 100 times a month.. if I average (2+100)/2...=51. 51 times per month on average for let's say half of that 23 years.. and I'll take just twice a month for half of the 23 years because hey I was busy too..lol.. so .. 23/2= 11.5. 51x12x11.5= 7038. 24x11.5=276. 7038+276=7314. So, I estimate 7314 times in my lifetime so far. Wow.
