This is a very good thread topic Ygrec23. I'm not in my 60 yet but I do want to be a healthy elderly person. I don't think its too late to improve your lifetyle with healthier habits. Its well known exercise improves the brain and you should look for other seniors you can exercise with, because people are more likely to keep it up if they have someone who's counting on them. Using weght resisitance is also very important since we start losing muscle after 35. This is one of the main reasons seniors fall - because they're too weak to balance or save themselves when they're about to fall.

I recommend not to drink alcohol - not good for the brain. You can also look up Brain Plasticity and PBS had shows on this topic. There's also books on a brain healthy diet. Learning a new hobby or anything new, like a musical instrument or language stimulates the brain. If you live near a mall, many communities have a mall walker seniors group.
