Key points from article :
Complexity of the regulation of ageing programs may be much greater in humans as compared to other species.
Humans were not really meant to last beyond their 50s.
In humans, the molecular responses during ageing don't follow a linear pattern.
Many little-studied so-called non-protein-coding genes are involved in human aging.
Aerobic capacity and insulin resistance interact with some of the same genes as aging.
Most valid of 'anti-aging' programs are naturally active in humans and stop when we reach our 50s.
The study was published in Aging Cell journal.
