Well, back in those days we had a thing called "common sense." Now, that fell outta style with the newfangled age of Whippersnappers.

Today, we find that a lot of the things we learned not to trust, are now things people have fallen for hook, line and sinker.

In addition, and in conclusion, the straps on boots these days are of inferior quality and they just can't be trusted for the task of self levitation even if you had the grip strength.
