Lots of changes.
The poster child of aging seems to be a wrinkly-faced, forgetful, grumpy old man. But science is painting another, more in-depth picture of aging Americans. The elderly tend to become more happy, liberal and in many cases remain pretty darn sharp. Here are 7 ways we change as we get older.
As wrinkles set in, so do a person's rigid beliefs, many people have long assumed. Not true, according to a survey of more than 46,000 Americans between 1972 and 2004. While the study didn't follow individuals as they aged, the results represent snapshots of the changing attitudes of respondents in different age groups. Over time, adults' attitudes got more liberal regarding politics, economics, race, gender, religion and sexuality issues. While the results don't mean your grandma is sure to revert to hippie-dom, on average older adults will head in that direction.
