Anyone involved in any form of sport and exercise knows the age-old acronym RICE. Rest, ice, compress, elevate. Damaged your hamstring? Your trainer will hog-tie it to your leg until it turns purple and screams with repulsion.

However, later that night, you’re at home watching reruns of Buffy the Vampire slayer, with the ice hanging there like a warm mojito, you suddenly can't remember what the trainer told you. Was it 20 minutes every 15 minutes, 20 minutes every hour, or an hour every 20 minutes? Furthermore, your partner no longer thinks it's cute that you're injured, and looking after you is getting damn tiresome.
