@artemis I just about cry when people take their bicycle to the bike shop and pay to have a puncture fixed. And don't even start me on whether chains need lubrication rather than frequent replacement. I'll help you learn! It's not hard!

I get the occasional free item that just needs a $5 ball bearing replaced etc. So in a way I'm perpetuating and benefiting from the problem.

But yes, too many things are designed not to be repaired when they don't need to be.
