A coworker of mine, Heather Platz is raising money to support an organization she is passionate about. Her son, Zeke has Down Syndrome, which is due to a third 21st chromosone, thus the theme "3.2.1 pledge":

The money for this goes to various individuals with Down Syndrome to help get them through school, and to help them reach their dreams of full potential living with Down Syndrome.
I donated 3 x $21 to this organization and pledge to swim 3 x 3.21Km workouts before the end of this week in a nod of respect to this organization.
