A study from London shows that women who are overweight or who smoke age faster, as measured by the length of remaining telomeres in their cells. Both smokers and obese subjects had shorter telomeres, which the study authors attributed to oxidative stress.

A doctor from Colorado has produced a pill he claims will reduce oxidative stress levels and help people live longer, healthier lives. You can buy into this dream for just $50 a month -- odds are that will make the good Doctor live a longer, healthier life, but will it do anything for you?
