Prince Charles catches a lot of flak for his flappy ears. If it seems like they're getting bigger, it's because they are. The large schnozzes on the famous faces of men like Adrien Brody and Owen Wilson are getting longer, too. You may not realize it, but ears and noses get larger as we get older because they're made mostly of cartilage, which breaks down and sags over time due to gravity.

One body part located south of the border also grows beyond puberty. Sorry, guys, it's not that body part. It's the prostate gland. Every man's prostate grows naturally with age, generally starting in their 30s. No one can post a meme of your outsized prostate on Twitter like they can for famous noses and ears, but for many men, this growth leads to benign prostatic hyperplasia (BPH), a noncancerous condition that interferes with urine flow. Obstructive symptoms of an enlarged prostate include a weak or intermittent stream and straining to urinate.
