Well SRD that's one which troubles me. A wee bit.
Boys 1-3 show no interest in taking things apart.
Number one lives in London and shows no interest in riding a bike there even though there is a Boris rack outside his door and I'd be happy to lend him a Brompton for a while. Numbers two and three like riding a bike and will ride one from school when I'm there but the memsahib is reluctant to even let them walk home and has only started doing that this year because of time constraints. Two is 11 and three is nearly 10. They went to Cumbrae last summer and loved it. They now want to cycle round other islands. Bute is a possible, Arran is 56 miles so they might need to work up to that one.
Number four on the other hand can build IKEA furniture and he's only 7. I don't let him do it unsupervised but he knows how to read the plan, find the bits and screw them together. He doesn't do hammering yet.
If I'm taking something apart he wants to know how it's done… and sometimes helps. He's seen tubes patched, brake pads replaced and the inside of 3 & 5 speed hubs. However, he's got a diagnosis of being high functioning autistic and we can't let him walk along the pavement on his own so he can't ride a bike. If he can watch me fettle then he does. He also wants to know what all the bits do. He's had a look at engines now and again but repairing cars has to be outside in the cold and often involves extended cussin' so he doesn't watch that.
If I'm in the garage then they all just play computer games with each other. I'm not interested in computer games so I suppose it's fair that they don't thrill to the improved design of the SA clutch.
