Maybe even thousands. Even better: you could live those years at your peak physical state.</p><p>At first glance, that's an absurd statement, going against the experience of all human history. However, Oxford University's Aubrey de Grey, a leading theoretician of aging, believes there is a 50 percent chance that someone alive today will live for 1,000 years.</p><p>Aging, according to de Grey, is essentially the lifelong accumulation of molecular and cellular damage throughout the body.

The answer lies in biochemistry.</p><p><br /></p><p>The cycle of colors in the leaves of deciduous trees is influenced by weather and temperature (more on that later), but one of the primary drivers is the lengths of nights and days, which govern a tree's growth cycle.

It's as if having a trusted caregiver nearby transforms children from scared toddlers into confident adolescents. And in a way, a new report suggests, that's what having mom around does to a kid's brain.</p><p>When they're first born and for years after, infants and young children can't do a whole lot by themselves. They can't eat on their own, they aren't very good at managing their emotions, and it takes a while for them to learn how to dress themselves.
