Are people getting dumber, or are there just more regulators and liability lawywers? Remember the old-time GE electric fans? These things had gaps in their blade guards big enough to stick your fist through. Metal blades, too. I don't think you could build something like this today without chopping up a large number of people, but I never knew anyone who actually stuck their finger in one of these. And how about the interurban electric trains that used to run in the US midwest (yep, we did have mass transit at one time)? They didn't even fence off the tracks in the countryside. If you did that today, you'd have a great, big linear "people zapper". But I suppose people back in the 1940s were smart enough to stay off the third rail. I just put in a ceiling fan that had the following warning on the blades: "Stop Fan Before Cleaning Blades." Sort of makes you wonder, doesn't it?
