I went to a restaurant for some take out last evening, and one of the patrons who walked in was a lady about my mom's age, early 70s, who was very big. Based on what my size was, I am guessing she was at least 450 pounds, if not more. Walking was not easy for her (though I don't think she had a cane or anything), and it just looked uncomfortable. I'm not judging her – I have no idea what her circumstances are, etc. BUT I easily saw myself in 30 years, if I don't continue what I am doing now for the rest of my life.
What that woman was enduring, my friends, is NOT how I want to end up. I want to be climbing mountains, running races, and surfing when I am 70.
