Please be careful what you post, my wife has been known to log on and browse.
You have just inadvertently divulged one of my most closely guarded secrets.
However, I have a slightly different spin, one which my wife has much more interest in than that saftey crap.
"I am saving us HUGE money by doing the work myself". I usually don't mention that I am doing the same thing over and over and over again.
Drilling little holes in stuff can kill many hours in the gararge. Then there is the tapping, many more hours.
Then greasing, more hours,
You can see the trend.
