What other Hobbies or Interests Do You Have?


Hello,
I was curious as to what other Hobbies or Interests do you have that also take up much of your time, energy and money or is Audio the only one for you?
Being a car enthusiast is definitely my first passion. Always reading about new cars and lusting after some classics.

For me, besides my interest in building a Audio System in the past few years, I am also a Car Enthusiast and Amateur Photographer (actually I hate using that term, more like a photo enthusiast because I consider myself a novice).
All 3 Hobbies have taken much of my time, energy and money. Sometimes I look back and think, wow, what have I done?
Could have saved all that money and time.
So I guess I should list my gear if I am talking about other hobbies:
Cars:

2016 Mustang GT 6 Speed (weekend car, a few modifications) and 2018 Subaru Forester XT (Daily Driver). Obviously both are performance oriented.

Camera Gear: Nikon D750 with Kit Lense, Nikon 50mm 1.8 Lense, Tamron 14-24MM 2.8G
Thnx

It is great to see so many cyclists. It is undoubtedly the best aerobic sport for aging humans.
I also had a Bianchi Infinito. Great bike. It had Campy Super Record EPS. I had to sell it. Mountain biking destroyed my right wrist. I am now the proud owner of the only Motec wrist arthroplasty in the US. I had to go to London to have the surgery. In the US they just fuse the wrist. The Motec is not available here. Swemac the Swedish company that makes the Motec has no desire to bring it to the US due to the liability. Think we have the best medical system? 
Anyway, I had to keep cycling but wanted to take as much stress off my wrist as possible so I got a Specialized S Works Diverge Frame. The Diverge has a shock absorber in the stem. I built it up with Campy Super Record 12 speed EPS Disc and Fulcrum Carbon wheels. It is the ugliest bike I have ever owned but it rides great and the Campy disc breaks are the best I have ever used. I still have my original Merlin Extra Light. The best Ti welding ever done. It is indestructible. It has been all over the world and I can not bring myself to sell it. I also have his and her Richard Sachs frames. I think about building them back up but they need their rear drop outs re spaced.
Go tubeless! I have never had a puncture fail to seal. I do not even carry an inner tube any more, just CO2 cartridges. Just for fun I rode a punctured tire and put another 500 miles on it before I get down to casing and I never patched the puncture!  They ride better, are faster and you never have to mess with tires and inner tubes on the road. My wife and I have put a combined 4000 miles on tubeless without touching a tire lever. 
Edzyn, IMHO Tazio is the greatest race car driver of all time followed by Fangio and Senna. The 1935 German Grand Prix is the greatest race of all time. Tazio wins it in an outdated Alpha against much more powerful German cars from behind! Keep an eye on Max and Charles!

We drive fast cars in the country.
Aside from our shared audio avocation, I used to be an avid motorcyclist: BMW, Kawasaki, Guzzi, Ducati. Still have my VFR800i but debating selling it... I figure next time I deal with gravity I might not bounce so well.
I've been collecting, repairing and yes, playing with Lionel Electric Trains (1945-1969) for 60 years or so.
Love shooting a round of Sporting Clays when I get the chance.
And I regularly enjoy an excellent whiskey with a good cigar!
Life does not suck.
