Everyone knows that exercise is part of having a healthy body.
Scientific research shows that an active mind can prevent senility.
A number of mentally active people were even able to live long and normal lives despite exhibiting the early symptoms of Alzheimer s Disease. Therefore, as a public service, it is my pleasure to offer you a selection of web sites designed to challenge your mental abilities and keep those brain cells healthy. What is without doubt true is that very high proportions of these folks are attracted to the Internet. One of their favorite pastimes is to challenge each other with a wide variety of mental puzzles and IQ tests. The stuff they post is a great resource for the rest of us.
