Playing at home...running the OPERA category on Jeopardy.
And, for good measure and also once (but will very likely do again):  go to an opera.
By choice, getting up in front of a crowd (about 50 people) to give an extemporaneous speech.  This was 16 November last year, in a park event here, talking about the newly-elected-at-the-time guy who I call Agent Orange.
Been to Key West.
Had a building put up, new construction built-from-scratch.  (In 1990; the smallish pole barn I'm using as a warehouse and office.)
Moved away from Michigan.
Moved away from Ohio.
Spent more than 24 hours (taking time only for reasonable breaks such as eating) in bed with a man.
Climbed more than 2,000 feet (solely by hiking) in one day.  Less than two years ago.
Had cancer surgery.  (Some things you hope you NEVER do or, if so, certainly not more than once.)
Bought a desktop computer.  (It's still running fine after eight years.)
Tried opium.  (I didn't like it.  All it did was put me to sleep.)
Been on television, in a broadcast.  (I showed up in the audience on the Merv Griffin Show, waaaaay back when.)
Been circumcised.
Suffered a broken bone.  (Some would say that circumcision causes a broken BONER.)
Had a "big" backyard satellite dish installed (which I used for about fifteen years).
Lived with roommate(s), other than college or family upbringing.  (This will change soon, and become no-longer-only-once, in Chicago.)
Found a restaurant that has ALL of my LIFETIME best:  fried chicken, lake perch, and walleye...that's my Holy Trifecta of entree-type food, and finding it this late in life was an impossible achievement, after eating in hundreds if not thousands of restaurants over the years, but it happened.  (in Markesan, Wisconsin)
Going "east" while flying WEST (flying to Australia).
Had (partial) dentures made for myself.
Testified in a courtroom.
Became a JUB member.
Had severe car damage from hitting a deer (or other large animal).
Saw Pansy Division performing live.  (Gay punk band in the 1990s.)
Driven non-stop entirely across a time zone, ending up with a two-hour shift.  (I consider the 15-minute "power nap" in Salt Lake City to be reasonable; that was basically the midway point between San Diego and North Platte.)
Received Australia on TV, using conventional "analog" TV and outdoor antennas.
Been a resident in a mental institution.  (During my puberty; my entire "8th grade" year was there.  I didn't like it at the time, but my "20/20 hindsight" opinion of the experience is VERY favorable.  Without it, I doubt I would be alive.)
Baked a pie.  (Yes, only once.,)
Watched my country commit suicide.  (Opinions may differ.  R.I.P. United States, 04 July 1776 - 08 November 2016.  It's the beginning of a SLOW suicide, but it counts.) 
Traveled more than 100 miles on a bus in one trip.
Punched back on a bully.  (I haven't hit somebody in more than fifty years, now.  Considering other people's experiences, I was VERY fortunate not being in bully situations very often at all, in my lifetime.)
