I suppose during the Roaring Twenties a 10-year-old girl could do the Charleston on the top wing of a biplane without her parents being arrested for child endangerment.
These days her 10-year-old great-great-granddaughter cannot not play alone in a city park without someone complaining to the police.

That is nothing. Check these daredevils out.

BTW after watching this I do not wat to try dancing on wings.

"couple is being chastised for"
Assuming it exposes only the participants to risk, no one has the authority to chastise them. I'd hate to see the authorities get involved in stopping them.

Maybe they are newscasters and took their stupid pills!

Usually it is not immediate relations who are affected.

It is innocent people who happen to be nearby or wander into their path while committing these idiotic stuns.

I don't mind if they remove themselves but there is almost always someone else affected. They don't think of loved ones, friends colleagues who are impacted by the actions.
Self absorbed narcissists totally oblivious to the feeling of others. As I said prime candidates for a Sarwin Award.

There are so many idiots on this planet.

This one is the species I encounter frequently, who does things mindlessly and on the spur without ever thinking of consequences.
