I can relate - I'm 56 and notice it's harder to keep up sometimes. I recently was on Pinterest and came across a neat site called DaisyBrains. They have really interesting brain games and what I best is that they have a number of exercises specifically to work on memory skills. I signed up for an annual membership yesterday - I've been reading that we have to keep our brains active - after all we will probably live to be 100.
A survey tells you best memory originates from good sleep and diet.Having a regular stroll outside is also dispensable to keep a good memory.Let alone above measurements,sometimes a medical equipment such as Cavitation machine posted on http://www.gzoyaga.com/ProductsType/Cavitation-machine-.htm ,by which you can help improve this situation.
