It took me a few hours to recover from one free dive to 100m. A helpful Dive Doc told me our lungs are compressed to just 20% of the volume at that depth.Quote:

Scuba is usually not so deep. Dive tables and timing is critical for most depths. It gets almost pointless at 40 metres with just a few minutes on the bottom with normal air diving. Diving Tables show this well Dive Tables

Mixed air SCUBA is able to go deeper- gets very specialized and for 99% of divers not a lot of need. You could breath from my dive cylinder for over an hour or two on the surface easily. At 20 metres I get just under an hour as long as not breathing to rapidly and keeping my heart rate reasonable- This is very much a goal in running for me as well.
PS If you ever get the chance to hop in a Hospital Re-compression chamber do it- Nitrogen narcosis is the best fun you can have with your pants on IF its done when NOT diving. I have helped a few divers with it at 27metres usually. I have not had it in the water myself! Nitrogen narcosis is not really free diving issue.

The people in this video did not have a HUGE Clearance Dive I had in the Dive Chamber who had a deep booming voice turn to Donald Duck like. Add your own laughter is Donald Duck like to really kick it along[bigrolf] In case your wondering they hold their noses to clear ears or equalize the pressure in thier sinuses. If not done PAIN and aural barotrauma would occur.
I'm more than happy with my 12 metre limit (by sounder), whilst recovering fishing gear that some dopey pillock had knocked overboard.
I was solo too. [biggrin]
Trivia then is Olympic diving pools are perfect for you then Diver Saitch[thumbsupbig] Noted when at a Olympic diving pool doing training for a month that very few people could dive as deep as you can Sir. Bravo Zulu.Quote:

Oh, no, now we are going to have to add a new month into the calendar. Roman calendar - WikipediaQuote:

I did visit Japan a few years ago. Bins were very infrequent! It was very very clean- Clean up Australia could benefit from good examples [biggrin]

PS they lost "Japanese fans who had just spent hours bouncing under a blistering midday sun allowed themselves a moment to wallow in the disappointment of their team’s 1-0 loss to Costa Rica."
A tesla truck made its first 500 mile loaded trip. 80,000 lbs class 4 (36287.39kg) Might be 81,000lbs.
The capacity of load is significantly less than current trucks of the same size due to the battery weight.
Other thing of note is Melbourne to Sydney is 878 kilometers (546 miles). Close but no cigar?

Having the battery go flat at the bottom of the Dipper could ruin your whole night.Quote:
