from Mental Floss - The loops first became popular among naval sailors, who didn’t typically have much closet or storage space available for their uniforms. To make putting away and drying their shirts easier, the loops were included so they could be hung from a hook.

Read the article Hedi linked to. People made up all sorts of stuff about having one/not having one. Some manufacturers actually sold just the loops so shirts would not get ruined. We really suck as a species.
I had to go look... Yes, they do suck, and as of now there are about 850 documented tick species!!! I also learned a new trick for safely removing them: When you locate an attached tick, immediately grab a cotton swab, and gently twirl tight circles around the wound, lightly pulling at the tick. The goal here is not to pull the tick free, but to cause it to release and latch onto the swab. It should happen within moments. You have virtually no risk of leaving mouth pieces in the wound, since the tick detaches itself. Everyone seems to have a "trick" to de-tick. I've never heard of using a Q-Tip before.
And now, back to Random Memories. I remember every Monday my mother would strip the beds and wash all those sheets. Then the clothesline would be sagging with the weight of them while they flapped in the breeze. I couldn't resist running through them as they dried, and I still remember that fresh scent of my pillow with the clean linens.
My memory was not that far back. I didn't have a dryer before I moved to this house. 20ish years ago. My sister smelled the towels and wanted to know what laundry detergent I used because they smelled so nice. I line dried them
