Embrace makes it very easy to monitor physiological stress, sleep and physical activity.
You can check your entire day in a glance in a way that is easy to understand.
If you push yourself too much, the Embrace will gently remind you with a vibration that you need some time to recover. You can customize it to suit your behavior and needs.
I recently met a mother and daughter team who participate in a wonderful organization called Canine Partners for Life. http://www.k94life.org/html/seizure_alert.htm
