Most people experienced this with Mike Tyson I believe. I mean Mike is an old guy, out if the blue he decided to fight that young boxer, Jake Paul. Jake is well built, young and trained. Mike is a legend but old and no matter how much training he does, he won’t get any younger.

Some people made a bet on Mike’s victory. The nostalgia fooled them into thinking Mike could win. Didn’t happen.

Jake wiped the floors with Mike.

Some people lost serious money.

It proves OP’s point. Don’t get stuck in nostalgia.
