If something is going to be thrown away otherwise, I like to have a look inside to see what the problem is. Sometimes it's easy to fix. Sometimes I see a glaring design fault that I can fix easily, e.g. pathetic little microswitches that I can replace for a couple of dollars with decent ones. Usually it's quicker to fix the device than the hours required to go and buy a new one and disposing of the old appliance. But it's as well to know about potential dangers with some things, e.g. microwave capacitors, those big springs on garage doors, standing under a crane or helicopter that is lifting an anvil, etc etc!
