Classic cars, if you're into cars. Think older Porsche 911, muscle cars, Broncos, old pickup trucks, etc. This is not mine, and probably not $35k, but it can be an investment that you can have a lot of fun with. https://ibb.co/Vcby0WXC
I have a motorcycle lift and a car lift, but the desk is great for motorcycle engine rebuilds or working on a steering rack, just like a normal workbench but you can raise what you're working on to chest high instead of bending over all the time.
I love them, I have one at work and three at home. I end up standing about 80% of the time and I feel that I'm more productive when I'm standing. When I sit at my desk, I tend to try to get comfortable and slouch a little in my chair, which makes me want to be lazy.
A big plus I found is that at work, it is much easier to show someone a coding problem or something I'm working on if the desk is at the standing height. It's kind of like working on a whiteboard.
Both my wife and I have adjustable desks for our home offices, and my wife doesn't even have a chair with hers, she's always standing.
I was able to get a used one from my last job after they remodeled our offices. I'm going to use that one for my garage workbench. I weigh 230 pounds, and just for fun, I wanted to see if the desk could lift me, so I sat on it and my desk had no problem going up and down multiple times. That made me have the idea it would be a perfect workbench for working on my motorcycle or car parts.
This is true, and there are many strategies that hedge funds use besides just buy(long) or sell(short) the market. High frequency trading is one, another is spread trading. With spread trading, you take 2 stocks that are highly correlated to each other, let's say Ford and GM. You buy one, and you short the other. You are technically market neutral, so if they both go up or down, you are still break even. When the 2 stocks start trading closer or further apart by a couple of standard deviations, you can put on a trade that bets the 2 stocks will revert to the mean of their historic ratios.
