4 Shots & Sore Legs

It was time for the yearly physical check up for the young man. 45 minutes & four vaccination shots later he left the Dr. office with stickers and sore legs. Good thing is that next time he'll get a boost of the same vaccinations he'll be 7 years older, but he has to be back next month for a flu shoot, and the following month for a swine flu shoot. I wonder how many shots the average person gets in her/his lifetime?
