I started boxing when I was 11 years old in a gym with my late dad's guidance. I kept up boxing until 14 years old when he died and I changed to bodybuilding. I probably won't be a good boxer at 6'2.5" tall; I was made for bodybuilding with the bone structure and ability to add fairly easy.
But he showed me the effects of tats when guys get older. Dad told me you don't want to look like those guys when you get older with the droopy tats.
So, I still respect his wishes decades later.
Rest in peace, Dad.
