Yeah, I’ll never understand this phenomenon. It actually happens to a lot of people who were athletes in high school but never make it to the collegiate or higher levels. I think what happens is they stop with all the physical activity, along with metabolism slowing a bit naturally with age, but they continue to eat the same amount of calories, and trash they always did. I’ve seen it happen to a few old friends. Not making excuses, just an observation. It even happened to me for a short period before I woke up one day and was like WTF am I doing? The real issue is it creeps up on you slowly before you notice it, and unfortunately, and often times, the ones closest to you who should jump your ass about it, won’t. They don’t want to “hurt your feelings”, or come off like an asshole.
