Never. It survives until it's dead. It's a finite point.

... I just want to bring a different, but ultimately inferior point to the first response. I'll be going now.

Depends on what you eat to be honest.

Your body stops being able to store calcium after age 30. So supplement up when young.

Your body has cell senescence, there is a limited number of times your cells can divide. Anything other than skin (and perhaps liver?) can actually never regrow. Any muscle and subcutaneous damage is pretty much permanent and just gets filled in by scar tissue. I do think numerous surgeries is going to decrease your life expectancy. The way I see it is actually a quote from the Hobbit "Getting old is like spreading butter too thin over toast, scraping and scraping." The more damage you accrue and the more cell lines start to die out it requires the remaining ones to pick up the slack in old age. Eventually you are just spread too thin. I'm 27 and look about 20 :). I don't have bad knees or bad elbows or whatever since I've avoided pretty much any injuries. I'm not the rambunctious type who hurts themselves all the time by playing rec sports too rough or whatever.

27 is still young. Genetics is the deciding factor. i know people who are in their 40s and they look great.

My buddy who is 32 has little hair and a big gut. :)

Your body is dying from birth. This chart explains it.

Depends, the brain is part of your body.

In some instances things can be disputed.

Best response in this thread. There's a great radiolab podcast about this. http://www.radiolab.org/story/91562-mortality/

Scientists were able to get tapeworms to live 20 times longer by increasing the number of times cells can divide. The issue with this technique is the facilitation of cell division is also what leads to cancer.

This limit to cell division has been shown to be due to telomere shortening. Your DNA has a segment known as telomeres. You start off with a set length. Aging and stress breaks down the telomeres. Once the telomeres shortens beyond a limit, the cell stops dividing.
