Yes this is why lots of men are into mechanics, its cool stuff. I get just as many "who is hiring these incompetent engineers?" though: In the last 10 years maybe less than 5 percent of those "tear box open" tabs has ever worked properly. There are suppose to actual engineers coming up with these cardboard box designs. I see bags with integrated ziploc, where the CUT HERE is on the wrong side of the ziploc. I see simple home plastic such as a water filter, where there are incredibly sharp parts right near where your hand holds the thing. What is going on? I thought junior engineers are complaining they aren't getting jobs? Seems like they are making everything these days.
