why do old men have big ears
The late baseball sage Yogi Berra once said that you can observe a lot by watching. And it's true. Watch a person age from 20 years old to 90 years old, and you may observe that the ears and the nose just keep getting bigger. was a prime example. Actually, there's a reason that certain body parts get bigger, or at least seem to get bigger, as we age -- but the science behind it all may surprise you. has the scoop in today's DNews report. For most people, male and female, primary development ends.
You're not likely to get any taller, and while your cells will continue to replace themselves throughout life, you're no longer growing as an organism, strictly speaking. So why do the ears and nose get demonstrably bigger as we age? It has to do with cartilage. The body has four basic
-- connective, epithelial, muscular, and nervous -- and each has unique properties. Cartilage is a connective tissue that can be thought of as the body's duct tape. It's extraordinarily versatile and useful, and is used to patch together other tissue all over the place.
Cartilage doesn't have blood vessels or nerves, however, and as such doesn't age and heal like other tissues. As cartilage gets older, it undergoes a that makes it thicker, heavier and less elastic. As you may have intuited, the structural elements of your nose and ears are made of cartilage. So while nose and ears do get bigger as you age, they're not actually still growing. In fact, the enlargement is actually due to a kind of slow-motion reverse decay, in which the tissue gets bigger as it degenerates.

ORG: LifeBridge Health: Exploring Nature Educational Resource: In July 1993, 19 members of the south east Thames faculty of the Royal College of General Practitioners gathered at Bore Place, in Kent, to consider how best to encourage ordinary general practitioners to carry out research.
Some members favoured highly structured research projects; others were fired by serendipity and the observations of everyday practice. Someone said, БWhy do old men have big ears?
