This, like so much else, requires balance. I saw a commercial on television where a new driver had

a flat tire. He called his father who was instructing him on how to change the tire. His father asked if he knew what a tire iron was. The young man answered yes in an uncertain voice, while holding up a different tool. It was easy to see he was clueless. Here is where the balance comes in, you may not choose to change the tire yourself, but you should know the tools in case you have to.
