1. PORTABLE DEFIBRILLATOR The worst case scenario can be averted. Steve needs to employ a nurse to be with him at all times, ready to pounce with the Philips HeartStart Home Defibrillator should he collapse while ordering the Coffeee of the Day from the local Starbucks. Pay her minimum wage and you've got 24-hour-a-day Steve reassurance for less than 20k a year.
2. BLOOD PRESSURE MONITOR A cheap, standard high street blood pressure monitor would reassure us all of Steve's health. An Apple engineer could add a wi-fi adaptor and have it feed data to the Apple web site, letting the world see a reassuring count of Steve's current blood pressure in real time.
3. SHOEI X-SPIRIT CRASH HELMET If Steve was to fall over and bump his head, the results for Apple, its shareholders and fans would be devastating. We therefore propose that Steve encases his precious brain in a Shoei X-Spirit Helmet, the finest cranium-padding money can buy. You can't put a price on Steve's brain stem and frontal lobe! The matte black will also match his outfits.
