Interesting. Men are most at risk for aggressive prostate cancer if their waist size is over 37 inches. It may have something to do with cancer-causing hormones in fat cells.
Hmm...was at 38 for years, but this bike commuting has changed that. I bought a pair of 34" waist cargo shorts last week, put them on and they promptly fell halfway down my butt. I can fit both fists in the waistband easily. Haven't measured them, so they may have shrunk up a bit in the wash since then, but normally 34" anything would be "suck the gut hard and button it quick" even before shrinking. 36" waist Wrangler cowboy cut used to almost have the skin tight look going, but now they have to be hitched up every couple of steps until I find my belt.
