What’s One Invention I Could Not Live Without?

So what’s the one invention I could not live without?

The first thing that comes to mind is the shower curtain. The automobile and computer rank pretty high, as well. But I’d say the most important invention I could not live without is air conditioning.

I do not think most of the people I know would be alive without air conditioning. The population of the South would have continued to remain low. My parents would have probably never been born, so they would have never met and married. The same would have been true of other friends too.
