  • I’ve driven through Oregon before back when you weren’t allowed to pump your own gas and it felt ridiculous and inconvenient waiting for an employee to come pump gas for you. But maybe that’s just because I’m accustomed to self serve.

    For groceries it’s nice to have the option to do self checkout. If I have a small number of items then self checkout is faster/easier. If I have a large number of items then going through the line with the cashier is faster/easier.

    There are anaerobic bacteria that don’t need oxygen to survive. That was the norm before The Great Oxidation Event when cyanobacteria started releasing oxygen into the atmosphere during photosynthesis. Prior to that there was very little oxygen in the atmosphere, and anaerobic bacteria ruled the world.

    After the GOE the high concentration of oxygen killed off most of the anaerobic bacteria, and what was left were organisms that made a blood truce with oxygen. Aerobic organisms gained incredible power from utilizing oxygen for metabolism, but eventually die from the accumulated damage the oxygen does to them.
