The town I live in burned down almost completely in 1787, so most historic buildings in the city were built after that. The city wall is probably the oldest structure, but it’s unknown when it was originally built. The oldest building with a known year of construction is most likely the church that was built in 1246.

Not necessarily. If you have a lot of experience or a different perspective and you seem trustworthy to me, you don’t need to have a good argument. On the other hand, if someone else comes along with a good argument why your opinion is wrong, I will start doubting you.

For example, if you’ve been growing potatoes for 30 years, you don’t have to explain the biochemistry of potatoes for me to respect your advice. And if you’re a black person telling me that our town is terribly racist, I will believe you without needing a list of every single racist incident that happened to you.

I’m also a bit heavy and I know the struggle. I use a lot of energy just do prevent popping back up like a cork. I’ve considered using a little bit of lead, but what I like about freediving is not having a bunch of belts and vests and other gear on me. So I’m currently also trying to lose weight.

In the same vein, freediving is easy to learn up to a certain point and safe as long as you don’t hyperventilate and stay away from caves. Most people can learn to dive to 10-15m and look around a bit before they have to resurface. That’s far from breaking any records, but enough to have fun and see some cool stuff that you can’t see from the surface.

Plus, you don’t need any special gear, besides snorkel, mask and fins.
