Searching the web is GOOD FOR YOU!
According to a paper to be released in an upcoming issue of the American Journal of Geriatric Psychiatry, searching the web can improve brain function in older (55 - 74) adults.
It may even be better than reading or crossword puzzles because of the different sections of the brain it calls into use. Further, like most exercise, it seems that the more you do it (within reason - be carefull not to hurt yourself) the better it may be for you.
If you read sciam.com article linked above. It ends (for some strange reason) with the term "ROTFLOLing". Took me a while to "search it down"on the web. It seems to mean "Rolling on the floor laughing".
I point that out for the benefit of my fellow oldsters. Guess the youngsters in the crowd would already have known that.
Now to go search the web for some reasonable fuel oil prices.
