"A young woman wanted to cook roast beef for dinner but had never done so before, so she called her mother to ask for instructions. Her mother told her to cut a chunk off both ends of the roast before placing it into the roasting pan. The roast beef turned out wonderfully. The next day the woman called her mother again and asked "Why is it so important to cut the ends off the roast." The mother thought for a bit and replied "I'm not sure, but that's how my mother taught me to cook roast beef, we'll need to ask grandma next time we see her." Several days later the woman and her mother visited grandma and asked her why it was so important to cut the ends of the roast off to ensure successful roasting. The grandma replied with a smirk, "because that's the only way I could fit it into my roasting pan".
We so often do things the way we do because that's how we've always done them. We're not quite sure why we do things that way...but it must be the "right way" because that's how it's always been done.
Perhaps there are other options that make more sense for the ways things are today.
