@freebornangel is right, you're looking through the wrong end of the telescope.

A year to a 50 year old is similar to many other years, with plenty of examples on memory. What year was it that I got my leg operation? Two years ago or five? I remember it was winter, they might say.

It's also safe to say that a typical 50 year old has less impatience for life, and invests less meaning in the dramas of the day. Typical old timers seek peace, sameness and routine, whereas youth seeks vitality and difference.
