What is a PHB? I searched online, and found that it could mean bachelor's in philosophy (PhB) or polyhydroxybutyrate ( https://en.wikipedia.org/wiki/Polyhydroxybutyrate ), but neither makes much sense in this context.

This is not a criticism, but I’m amused that someone with an HN account as old as yours is just now finding out what “PHB” means.

My memory of PHB (from Dilbert) was overwritten with PFY (from BOFH).

Well, our brains are asymmetrical in terms of function, and our bodies are asymmetrical internally too (heart, liver). So, which came first? Are we mostly right handed because of left brain functionality (each side of brain controls opposite side of body), or is handedness innate in some other way and perhaps influences brain sidedness? Or, are these two things unrelated?

With so many poisonous plants reptiles and insects, it is better to use the hand further away from the heart. In case it gets stinged or bitten or pricked the poison will affect a slightly more remote area.

Im also like that..randomly mixed. I write left, but use scissors always with right. Throw and kick are right, but swing and bat is left. Computer mouse left. Taking a phone call is always left hand on left ear...but holding phone to use or text is always right hand. Self check out? Back to left hand for that mostly Lol. If a backpack is on one shoulder it feels weird if it's not on my left shoulder despite being mor…

I thought that scissors were made to be right handed, and you need a 'reversed' pair for left handed people. Or is that a scam?

It's nicer to use right-handed scissors left-handed because you get an unobstructed view of the cut line. The children's stamped ones hurt your hand and the ergo ones are impossible but once you learn to keep the blades in shear it's a better experience than lefty scissors.

There's a slight pressure you put on the hinge when closing them. The handedness aligns the pressure to a closing motion laterally (keeping the blades together) as opposed to opening (pushing the cutting edges apart). They do in fact make a difference. Trimming my beard with beard scissors requires a bit of a strange grip in my left hand to actually cut well when I switch sides.

Nail scissors can be quite the experience for a left-hander, instead of achieving the proper cutting/shearing motion it will just try to bend your nails due to the widened gap between the blades. A bit less painful but also annoying is cutting paper for the same reason.

But don't you use nail scissors with both hands, cutting the nails on the hand that's not using the scissors?

The trick to using right handed scissors as a lefty is you have to kind of pull in with your thumb where naturally you push down and out with your thumb. But once you figure that out, it isn't so hard. Still, my scissor game is laughable compared to my wife who can do that "sliding the open blade in a straight line to cut wrapping paper" thing that I always stuff up.

Just throwing in my left handed anecdote here: the bottom of my hand was always covered in pencil graphite when I was in school because your hand drags over what you've been writing from left -> right. Also ring binders were a pain in the ass (your hand is blocked at the left margin lol)

I'm also left handed and this was never an issue for me. You hold the pencil out from your fingers thus your hand is sitting slightly below the line that is being written, traveling over unused paper constantly. Only people that do that weird claw thing have that problem.

The trade off is that you have less visibility of the letters you just wrote, which can be annoying sometimes and lead to spelling mistakes.

The thing with scissors is, as a left handed person, you'll never find the "reversed" type so you learn to just use "regular" scissors pretty early on. This is probably true with a lot of things, honestly. Yeah I might theoretically be able to cut better with a left handed pair of scissors but since I've never come across a pair I never bothered. Things get much more interesting with more complex things like golf, sn…

Fly fish hemostats drive me nuts. The lock is much more challenging with your left. Fortunately they make mitten clamps that work well. Learning to whip finish a fly left handed was a challenge too, once you know you know; I had a miserable time trying to teach my right handed kids.

if you look far and wide you can find left hand firearms components but the price climbs up

Have you ever fired an autoloader made for a right handed person, left handed? It is truly terrifying the first time or two when a shell ejects and hits you in the face..

It's even embedded in our language — “Ambidextrous” means “both right” lol

And lots of people use “sinister” as a stand-in for “malicious” or “evil” https://english.stackexchange.com/questions/39092/how-did-si...
