Enjoy Life, It Goes By More Quickly Each Day

Have you ever observed that time seems to be going by faster as you get older? . .

[Some theorize that] we perceive time by comparing it with our life span: The apparent length of a period of time is proportional to our life span itself.

We perceive our first few years to be much longer in duration than the years that come later -- as the graphic above this shows. If you measure your life this way, in "perceived" time rather than actual time, half of your "perceived life" is over by age 7. If you factor in the fact that you don't remember much of your first three years, then half of your perceived life is over by the time you turn 18, Kiener writes.

In mathematical terms, our time perception is logarithmic -- stretched out at the beginning and compressed at the end -- rather than linear, in which each year has the same length. If you don't know, or don't want to think about math, it's basically the difference between the graph on the left, which is how time proceeds according to calendars, and the graph on the right, which starts slow and then ramps up:

More recent theories about how we experience time draw on psychology and science. . .

One idea is that the passage of time speeds up with familiarity. As we get older, things become more familiar to us, and time slips by as a result. There is some evidence that we tend to remember events between the ages of 15 and 25 most vividly because we experience so many new things in that time. A related idea is that we can actually slow down our experience of time through paying attention to the present moment, what people call mindfulness.

This might seem depressing -- it kind of is. But it's also a reminder to savor our time and remember that it is precious."

The Republi-CON 'Creationism' Myth

UPDATE:  For "a striking example of Darwinian evolution in humans", read the Washington Post, How a history of eating human brains protected this tribe from brain disease.  

It is also interesting if you have any interest in religion and societal development.

UPDATE:  A new video from science advocates Stated Clearly provides an 11-minute examination of the evidence behind the theory of evolution that should come in handy for anyone debating the issue with creationists.

"Thousands of observable facts from completely independent fields of study have come together to tell us the exact same story: all living things on Earth are related," the group’s founder, Jon Perry, states.

Read Raw Story, Next time your creationist friends reject evolution, show them this video:

"Evolution is nothing more than a fairly simple way of understanding what is unquestionably happening. You don't believe in it — you either understand it or you don't. But pretending evolution is a matter of faith can be a clever way to hijack the conversation, and pit it in a false duality against religion. And that's how we end up with people decrying evolution, even as they eat their strawberries and pet their dogs, because they've been led to believe faith can only be held in one or the other.

But there's no reason for people of faith to reject the mountains of data and the evidence of their own senses. Reconciling is easy: Believe, if you want to, that God set up the rules of evolution among His wonders, along with the laws of physics, and probability, and everything else we can see and measure for ourselves. But don't deny evolution itself, or gravity, or the roundness of Earth. That's just covering your eyes and ears. And only monkeys would do that."
