    Hello Mr. Fernandez,

    Your ASA Autumn Series presentation on “Teaching Brain
    Fitness in Your Community” was really terrific. It
    confirmed lots of information I already knew and
    taught me a bit as well. Very nicely organized and
    clearly explained. Thank you!

    Here’s my haiku:

    New information

    Synthesizing my knowledge

    A forward movement
