Who are you again?

Hey, I don't know about you but sometimes I have problems concentrating and remembering stuff.  Trust me, I can remember a bike route or calculate sales prices but sometimes I can't remember my keys, people's names, what I went into a room for, who people are, and what time I am supposed to be somewhere. Thought I might try Focus Factor and Sam's Club has a free sample.  You do not have to enter your member #.

Here's what their website says, "Have you nourished your brain today? Staying focused and on top of your game at work, home, and school is more essential than ever. Like other parts of your body, your brain needs proper nutrition to perform at its best. Give your brain the nutrients it needs with FOCUSfactor, America’s #1 brain health supplement.*"
