I wonder if Rim Tape might solve the problems I keep having with tires going flat so often? I would seriously enjoy spending an hour or so with you and a bike talking about the different parts, what they do, how they affect performance and that sort of thing. I feel like I would have a lot to learn. Even learning to change a tire would be helpful (I can guess, but it's been over 30 years since I've done it).

Feel like offering a class?
