The shopping cart, and I don’t mean the online kind, was not yet invented when John McCain was born. This makes him very old, which explains his increasing kookiness as the stress of the Presidential race wears on him.
Some other things that are younger than John McCain:
The area code (they had only just invented telephones a few years before)
Nylon (not the magazine, the material)
The Golden Gate Bridge

Thanks for the tag back, Franklet! xo
