Gluttony and sloth = disease. When THE SHTF so to speak, it will be extinction level in the US because folks are unhealthy. I am 115 lb. 32. Two kids. Exercise moderately. My kids are watching. They deserve better. I wear the same clothes I did at 17. And have endured hard stuff. But there are no excuses for letting yourself go. Just hard work and discipline. Your health is a BIG witness.
