Yes, former Apple AAPL CEO John Sculley is keeping active. 

Actually, he is somewhat of a serial entrepreneur. 

Sculley knows a thing or two about the healthcare industry as well as tech. He is an investor and chief marketing officer at upstart pharmacy benefit manager RxAdvane, which does battle with heavyweights Express Scripts (ESRX) and CVS Health (CVS) . "I think RXAdvance is the most interesting company I have worked at since Apple -- we are disrupting the most vulnerable and expensive area of the market." Sculley said he expects RxAdvance to boast $2 billion in contracted revenue by 2018 and $10 billion by 2020.
