By 2050, the UN estimates that as many as 3.2 million people will live to 100 compared to 316,000 in 2011. Also, a 2013 study from the University of Massachusetts found that 25 year olds today can look forward to "2.4 more years of a healthy life" while a 65-year-old today can expect to live 1.7 extra years - than people who lived 20 years ago.
A study on 1500 women age 64 to 95 have found that those who spend sitting for more than 10 hours with exercise for less then 40 minutes a day have cells that are biologically eight years older. Normally as people age, the cells get older causing telomeres to get shorter and more frayed, but researchers have found that the women, with an average age of 79, have greater degree of damage to their cells if they lead a sedentary lifestyle.
Researchers reveal secret to live past 100. Genomic analysis has identified several new genes that shield the centenarians against the effects of aging.
Study shows deleting certain genes could extend lifespan & 189 of 238 genes identified have been linked to aging. Deleting LOS1 extends lifespan by 60%.
When you have a high school reunion, do you notice that your friends born within a year of each other look older than the other? Well, if your eyes can't perceive enough of that, scientists have finally proven aging process widely varies among people.
