Someone else in this thread mentioned diving. When I was doing my advanced open water course, we did an exercise to demonstrate nitrogen narcosis. Super simple test: we had a card with the numbers 1-16 written on a 4x4 grid in random order. You have to tap the numbers in order and it’s a timed exercise. We did it on the surface in the boat and again at 30m depth; my performance was maybe 20% slower, my buddy was more like 40-50% slower.
- p1necone 3y agoWouldn't being underwater make you slower just due to the extra resistance of water vs air?
- eru 3y agoJust being submerged in the water is probably what they mean by 'at the surface'. The resistance shouldn't change much whether you are 30cm in the water or 30m.
- tonyarkles 3y agoYeah, apologies, we did the first round about 6 feet below the surface. For me, at least, the resistance wouldn't have made a huge difference anyway; while some people suffer from nitrogen narcosis and don't realize it, I definitely felt mentally "slow" while doing the test at depth. It was frustrating knowing that, 15 minutes earlier, the task felt easy but at depth it felt really mentally challenging. While I was only about 20% slower, the qualitative mental effort was drastically higher.
