So I signed up on a mind training website (luminosity.com) that provides games that apparently improve brain function in the fields of problem solving, calculation, memory, flexibility, speed, spatial recognition etc. I played more than a few games...
Be warned, because its fun, it is also a little addictive .

The main problem with the games is that you need coordination and dexterity with a computer keyboard and mouse to perform some of them well...but I'm hoping that maybe that too will improve with practice.

I'm going to give it a try for a few months...anything that might help maintain and maybe improve what has been lost.

Thought that some might like to check this sort of thing out for themselves.

With love, Erika
