I’m 62. After reading everyone’s posts I have a few that others mentioned and a few that they didn’t.
Suit - I have a black one and a grey one for formal events. Currently in style but I don’t mind being the old guy in out-of-style clothes if needed.
CDs - over 1,000 in the basement but only players are in the cars. Love being able to ask Alexa or Google to play a song and it immediately starts playing. My wife buys CDs/merch at concerts to support artists though.
Vinyl records - again a basement full but nothing to play them on. The kids have players and buy them. I’ll leave my collection to them when I go.
Motorcycles - with the way everyone drives these days, road bikes are too dangerous and my body can’t take dirt bikes / off-roading.
Firearms - no longer hunt and what I have is plenty for target shooting and home defense.
Camping gear - still hike a lot but no desire to sleep on the ground anymore (and even more importantly neither does my wife).
Bicycles - I ride quite a bit for health but have a good bike that should last me the rest of my life. Have to get new tires, chain, etc. every year or two but the bike should outlast me. My wife has an e-bike so she can ride with me. I might have to get an e-bike if we keep riding later in life.
Books - haven’t bought a book in years. Love to read and prefer paper over electronic, but our local library shares books with all the libraries within a couple hundred miles. All I do is request a book and within a week or two it’s delivered to my local, small town library.
