Boston Celtics’ strength and conditioning coach, Bryan Doo, used an AED to save Chuck Conley’s life at Newton’s Hyde Community Center. The AED was placed in the gym by a local doctor after a friend of his died in the same gym during a game.

The photo-receptivity of the "eyes" of other species also varies considerably from that of humans and so results in correspondingly different color perceptions that cannot readily be compared to one another. Honeybees and bumblebees for instance have trichromatic color vision sensitive to ultraviolet (an electromagnetic radiation with a wavelength from 10 nm (30 PHz ) to 400 nm (750 THz ), shorter than that of visible light but longer than X-rays ) but is insensitive to red. Papilio butterflies possess six types of photoreceptors and may have pentachromatic vision. [3] The most complex color vision system in the animal kingdom has been found in stomatopods (such as the mantis shrimp ) with up to 12 spectral receptor types thought to work as multiple dichromatic units.
