Triathletes love to track data about our human-machines (bodies), dont’t we? How can I pass up getting a Sleeptracker then? I have wanted one for several years! I’m thinking this will be a good piece of gear to use this winter. Tera always gets mad when my alarm wakes her up at 4:30am. This should solve that problem, and I’m interested in the sleep-science aspect. Why not put ut on the Christmas list of your favorite triathletes? Of course, data charts will be available if I get it.
