Question

How can lifestyle choices affect memory in old age?

Answer 1

Same goes for drugs and diet.  If you put drugs in your body, you will definitely lose brain cells.

If you don't nourish your brain cells with nutrients, you will lose them.

Answer 2

Ever heard, "If you don't use it, you lose it"?  That refers to the brain too.  If you sit and stare at the t.v. all the time instead of reading, writing, and conversing with people, your memory will decline.  Keep your mind active and challenged.
