If you don't want to get the dementia and alzheimers in the old age. 1. Make sure to meet 1 new person each month. 2. Talk to people, kids and the relatives. 3. Solve puzzles. Solve small set of problems every day. 4. Socialize when you want as often as you want. I have seen a lot of people as they move to the old age having this dementia problem. Make sure to take your time to socialize and keep functioning. Keep the will of life alive. :) Image Credit: dreamstime.com
