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.

Same here, I have one idea for a simple 2D game that I would like to make just so it exists. I even got myself Unity (before they stopped being cool) and tried to do some tutorials, but I just don’t have what it takes.

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.

They’re only down there for a very short time and they don’t have a lot of nitrogen stored in their lungs, so decompression sickness is usually not an issue. I think there have been a few cases, especially with repeated, very deep dives. But nothing you have to worry about as a normal hobby freediver.

Passing out at the surface is quite common though, but not due to decompression sickness. It’s the lack of oxygen that can happen when you have learned to completely ignore your urge to breathe and then stay down for too long. The reason why you pass out at the surface and almost never at the bottom, is because the water pressure compresses the air in your lungs. At a depth of 10 meters (30 feet), four liters of air in your lungs are compressed down to two liters. This is basically “concentrated air”, which contains “concentrated oxygen”. If the air is compressed to half the volume, it’s like having twice as much oxygen in it. Then, as you ascend to the surface, the air in your lungs expands again, turning the concentrated oxygen into regular oxygen and then it’s just not enough anymore and you pass out.

That’s why it’s recommended to always have someone with you who stays at at the surface and who can step in if you pass out, keeping your head above the water. It has never happened to me, but I’m really a beginner and I still have an urge to breathe that forces me to go back to the surface after a short while.

You can go much deeper than 10 fathoms without supplemental oxygen, half the people reading this right now could do it with some training.

The world record is 117 fathoms on a single breath.

I think both torx and pozidriv have their place. Torx for any screw that needs a lot of torque, is in a hard to reach place or for really small screws.

When I have lot of screws in a simple application, like driving them directly into wood, I prefer pozidriv though. Due to the conical profile, the bit just automatically slides in correctly. Also, torx just has way too many different sizes.

Fuck Philips. Pozidriv is so much better.

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.
