    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 genial idea
