What other Hobbies or Interests Do You Have?

Audio is my first passion, 50+ years and counting.

Cars: I have two Corvettes, a '68 427 convertible was my first car have had it 45 years. And a '16 Z-51 coupe which I've been on the track with.
I did a body-off resto on the '68.

A couple of Harleys: '76 shovel head chopper and 2003 Heritage Classic cruiser. I built the '76.

I've spent way more dollars on cars and bikes, so does that make them
my #1.  No.  Love the audio, plus you don't get pulled over for playing to loud.

Competitive revolver target shooting, reloading, practicing at my private club outdoors, almost always alone. Very relaxing due to the concentration required, everything else melts away.

And cooking/grilling/BBQ and photography and beer and attending Mensa events.

That concludes my therapy session for today. Thank you.
  

Barts the 68 is my absolute favorite vette! It would round out my trio of a Singer 911 and an Eagle Speedster XK-E. Time to go out and buy another lottery ticket. 
Geof3, my oldest is a starving actress in New York City. She was Vivian in The Marvelous Mrs Maisel. I have terminal stage fright. 
gkr, Bee keeping? I won't do anything that requires me getting into a hazmat Suite. Do you sell the honey? 
Audiobill, you sold your woodworking machinery? All my work as a doctor is going to wind up in the same place, 6 feet under. But the pieces I make could live on forever.  
Gavman, let me know when you are visiting the US!
Danvignau, humans are now living in an environment they did not evolve in. As a result they are dysfunctional in many ways. Under the dysfunction is usually some instinctive process gone awry. Obesity is an example as are women preferring to drive SUVs (they like being up higher and men displaying that they are the most frightening powerful SOBs in town. Women spending a gazillion dollars on make up and on and on. A great question is, Why are we so fond on music?  Itis a universal trait in us. Where did it come from. My personal theory is that there is music in nature, a bird communicating by singing. I think before we invented words we communicated the same way. There was a sequence of notes that said "Danger" and so forth. Certain tribes communicated with drums. We can relax when we have an advanced warning system. We relax with music. Just a thought.  

My work is most of my passion: (1) high-throughput multi-omic analysis, (2) psychotropic drug discovery, and (3) formerly trauma neurosurgery and psychiatry.

My wife, son, and I have done some club-racing: 930 Turbo S2, 911 RS America, 993 Turbo, 996 Turbo X50, 997 RSR, 997 Turbo (2), and a Ruf Yellow Bird 996 (996 Turbo, >700 bhp).

I also like bird watching, but not hunting (not a political statement here).

I have too many hobbies and I'm sad that they are all expensive and I am retired on a fixed income... High End audio, Photography, Computers, Slot Cars, 3D printing, guitars and cars. I dont have one now but I've been a Porsche fan most of my life. My last one of 7 that I have owned was a 2013 911 Carrera Cabriolet. Amazing car! Maybe if I win the lottery....

"...but curious if all of you consider yourself highly addictive personality types?"

Not at all.
