Everyone knows that laughter makes a person feel better. The question is, how can it improve a person's life? People who
laugh a lot are healthier than those who rarely laugh. A neuroscience center in Michigan found that humor may improve the
cells in our body that fight infections. In addition, laughter improves personal relationships. A local high school newspaper, the
Beat, interviewed several teens and found that those who laughed often reported having a close relationship with their family
and friends. However, boys do not seem to laugh as often as girls. A recent study by Peter Roberts PhD showed that women
laugh over twice as much as their male peers. So how can we laugh more? Some people encourage laughter by tickling.
However, as people get older they become less ticklish. Betty Gain, a businesswoman, says that her husband is less ticklish
today than he was 20 years ago.
