You will be happy to know that I have figured out a way to lower the setting on the heart rate monitor to just under 80 BPM. Just an FYI, cats have a fairly rapid heartbeat. I little bit of research would have saved me some time and a fresh razor. Strangely, my dog will not leave my side, and unfortunately I am still looking for my cat. But seriously, the longer I wear this damned thing the harder it is to take off.....my Precious. I don't think I can sell it, nasty little thieves, ....I must get rid of it!...No! Don't steal my Precious...
