For me making the bed makes things a little nicer and gets me rolling on doing other tasks. First accomplishment of the day and it takes 10 seconds.
Also and maybe more importantly, it will keep dust and spiders and other insects off the sheets I lay on/in. If you’ve ever got dressed or folded laundry in a sunny room yoh will see how much dust everyday moving around generates. Those dust particles are skin cells (human and animal), bits of fabric, hair, and plastic microparticles since so many clothes are made from plastic.
Technology is better, crime rates better, environmental issues were better, LGBT rights and racism seemed better. But the gap between rich and poor has grown, wages have stagnated. And now I fear we are regressing.
