Mekong Posted June 27, 2023 Report Posted June 27, 2023 Would be funny if it had correct caption, it was a Submersible not a Submarine Submarine has enough power to leave port and come back to port under its own power, therefore can drive independently to the bottom of the ocean and come back. Where as a submersible has very limited power reserves so it needs a mother ship that can launch it and recover it
Coss Posted June 27, 2023 Report Posted June 27, 2023 Just passing the joke/meme along, not one of mine, it woulda got corrected if I'd a made it. 🤪
Mekong Posted July 7, 2023 Report Posted July 7, 2023 An exercise for people who are out of shape: Begin with a 2 kg potato bag in each hand. Extend your arms straight out from your sides, hold them there for a full minute, and then relax. After a few weeks, move up to a 5 kg potato bags. Then try 25 kg potato bags, and eventually try to get to where you can lift a 50 kg potato bag in each hand and hold your arms straight for more than a full minute. This is the level I am right now. Once you feel confident at that level, put a potato in each bag. 1 1
