7th Sign

You blurt out, "Hey , turn it up!" Too many concerts, disco nights and Walkmans have taken their tolls. First you lose the high frequencies and miss parts of the words, especially in a noisy room. It's embarrassing and frustrating," says Kenneth Einhorn, M.D., a hearing doctor. "We're seeing men in their 30's and 40's with high frequency hearing loss that typically would start in a man's 50's and 60's."

How to Delay It

You can't reverse hearing loss but you can learn to compensate for it. Stand 3 to 6 feet away from people when you're talking among them. This will train you to take visual clues from their body language and facial expressions.

8th Sign

Wrinkles start to appear. Wrinkling starts after 30 for most people. It could be a lack of hydration, a breakdown of collagen, a loss of subcutaneous fat. But it's most probably the sun, which is responsible for almost 90% of age spots.

How to Delay It

Moisturize! Any moisturizer with sodium PCA (most name brand moisturizer have it) "it penetrates the pores, drives hydration in and maintains it within the skin," Dr. Klatz says. You can grab a tube of alpha lipoic acid cream and put it on after you shave. "It can reduce lines, wrinkles, even scars."

9th Sign

Yesterday basketball wreaked havoc on your body. You used to play regularly; now you play only when there's a solar eclipse, a tsunami, or a volcano eruption. Playing an intense game after leading a sedentary lifestyle can cause multiple microscopic tears in connective tissues in the muscles. You don't feel it as it happens but you feel it during the next 24-48 hours. "The first few times you start moving around, all the scar tissue breaks loose and sends a message that you're sore," says Pearson.

How to Delay It

Don't wait until the next day to pop some pain reliever. Taking it immediately after the game can lessen the inflammation in your damaged muscles. Next time warm up properly before a game and stretch thoroughly. Cool down as well.

10th Sign

You decline to bungee jump. You're acting like a baboon, seriously, and almost like other species of mammal, says Robert Sapolsky, Ph. D., biologist at Stanford University. And that's good. In all animals, there's an aversion to novelty and risk after early adulthood. Nobody's figured out whether it's a change in brain chemistry or a psychosocial thing, but it's universal.

How to Delay It

Why bother? You've significantly reduced the chances you'll die like an idiot. Age isn't that bad, after all.
