NEW YORK TIMES: It is inevitable. The muscles weaken. Hearing and vision fade. We get wrinkled and stooped. We canâ€™t run, or even walk, as fast as we used to. We have aches and pains in parts of our bodies we never even noticed before. We get old.
It sounds miserable, but apparently it is not. A large Gallup poll has found that by almost any measure, people get happier as they get older, and researchers are not sure why.
â€œIt could be that there are environmental changes,â€ said Arthur A. Stone, the lead author of a new study based on the survey, â€œor it could be psychological changes about the way we view the world, or it could even be biological â€” for example brain chemistry or endocrine changes.â€
