This is why I keep to shallow freediving or snorkeling. There also isn’t anything of value to see in the water here which helps. Sometimes the water is almost clear enough to see your feet. Did manage to swim through a school of tiny fish before.

Not having to surface as often could be nice, but most ways of doing that involve quite a few risks and/or costs, so a snorkel is probably the best choice.

Certainly not.

The first time I read how to make thermite, smoke bombs, etc… I definitely was too young to fully work out the ramifications of my actions.

With that said: how many people ignore warnings that are clearly posted? That’s a human flaw. It’s not age gated. Needing to see for ourselves that the stove is hot sometimes is the only way we learn. Acknowledging this - does it mean we shouldn’t provide the knowledge because somone may do something stupid? I don’t believe that should be the case.

In short: people are going to do dumb shit - but I don’t think that means we need to over engineer the world to protect them from themselves.
