My question to you is: WHY?
You retired and you claim you amassed some wealth, at least sufficient to live comfortably until the bells are ringing (you claimed SEVERAL mm$). This means you probably generated this wealth with a higher ROI than 12-15%, probably through a combination of adding savings and returns from your investments through your investment advisor.
So, why would you want to get into a venture you know pretty much nothing about? I mean an understanding of options means nothing, in my opinion. Not looking down to you or anyone but it requires intensive experience to handle options profitably. Dont believe some kids here who daytrade (buy and sell) options and claim they know about options. Also, knowledge of some strategies means nothing. In order to profitably trade options you better have a DEEP understanding of the underlying probabilities, behavior of risk (not just first or second order but down to the 4th order or even more), and experience of several up and down market cycles to understand how options really behave in extreme market environments. Sorry, but its a joke as some claimed that all you need to know is how the stocks move without even mentioning the term volatility, this is ridiculous.
I warned you. You seem to like to pick up something that takes away your boredom and gives you meaning. There are thousands of other means to archive this goal. You seemed to have worked hard and I recommend you enjoy the fruits of your toil rather than getting into something that potentially takes a deep bite into your savings.
