I know of a few old blokes with money to burn that take up hobbies, cars, boats and even trains.Buffet just bought a share in a train set with all the track laid,signalling in place, scenery done and controllers.I know some out there will laugh but, when you see him beside the tracks with his engineers hat on you will know why.
On the other hand he does know how to make money so perhaps he knows something that the rest of us should look at investing in.I just wish I could afford ten shares.
