For me the harshest recognition upon retirement is the acceptance that almost all of my social connections were with clients - a fact which unwittingly unfolded to my initial disconcert when the relationship ended. Retirement was akin to dropping a tiny bowl of perfume into a sea of water - an immediate and utter dilution. When once I had overcome the reputed discomfort of this evolution my transition into the vaporized ether of retirement was considerably more favourable.
Like my learned friend I haven't much else to do either. However I don't use the lack of commerce to diminish the value of exercise for example. In fact I am rather proud to say I bicycle almost every day of the year. Acquainting myself with indolence has required substantial effort on my part - learning to listen to my appetite for an afternoon nap; to avoid accepting an invitation to a social gathering in which I have no personal interest; submitting to the luxury of reading or writing in the middle of the night over black coffee; limiting my agenda to matters of personal satisfaction or necessity; and refusing to buy semi-formal or formal clothing. There are as well certain mandatory philosophic admissions to be addressed: aging, mortality and posterity - virtually mirror images of what confounds one's thoughts at the other end of the spectrum (youth, life and the future). Insinuating the entire mess is the proverbial adage that we owe it to ourselves to relish whatever time remains. It's pretty clinical this business of living.
When not stewing over my current medical complaints, I divert myself by thrilling to the texture of the things which surround me - everything from art to music to literature to architecture to personal possessions to beauty of almost any expression. I feel I have awoken to a new scope of vision in my later years. For one thing, I have removed myself from the strictly proprietary attraction (in which I include the visceral seats of appetite). No doubt it matters that my sight is no longer fogged by distilled liquor, an elevation which has unfolded but gradually and almost imperceptibly over the past 5½ years.
I omitted to mention technology as a specific absorption. Technology has become the precious Persian upon which so many of the traditional sources of beauty and amusement reside. I listen to Ludovico Einaudi streamed from Apple Music through my AirPods on my iPhone. I read books from iTunes on my iPad. I capture photographs of my favourite landscapes and pictures electronically. My automobile is a computer on wheels, guiding me to my destination, keeping me between the lines and alerting me to obstruction. The latest culinary rage is non-dairy meat. I haven't yet discovered a workable pain killer - neither medicinal marijuana, hemp CBD nor whatever is currently being sold as legalized pot - but overall the progress is for me energizing if not indeed purifying.
