Two months ago, I heard from another OG who told me about a challenge that his instructor (Alvis Solis) decided to take on at age 46 because he was a little bored and wanted to do something momentous on his push to age 50. Alvis decided that he would compete in 50 grappling competitions by the time he turned 50. That's almost one tournament a month for the next four years!
