Elastic

Many people could argue about the single greatest invention of the 20th century, but unless they're thinking about elastic they're wrong. Elastic has become a very important component of my wardrobe. I could say it is because I have severe acid reflux and the doctor did tell me to wear loose fitting clothes, which is true. But the real underlying reason is this... "I ain't as good as I once was, but with a little elastic I'm good once as I ever was!" Seriously imagine a world without it, I don't want to it's scary!
