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 not a scam. My son is left-handed and his left-handed scissors don't work for me, while my right-handed scissors don't work for him. I have never understood why, though. In my mind, if you rotate the scissors 180 degrees, they should become the other kind (assuming the handles are symmetric, not those ergonomic asymmetric ones, I mean). And I just don't see why not no matter how hard I think. I'm not a dumb pers…
I'm right-handed, and usually use scissors with my right hand. When I try using them with my left hand, two things happen: First, they doesn't sit right in my palm, because of the way they are sculpted. Beyond this, and more importantly, they are no longer as effective in cutting things. Here's my understanding of why this is. When holding the scissors with your hands, in addition to the up-and-down force you exert o…
I write left handed, and use a fork in my left and knife in my right. Left hand for holding a phone or a drinking glass, and for shaving. I'm right eye dominant, though, so I throw, swing, shoot, use scissors, play instruments and use a mouse right handed. I'm not at all ambidextrous, I can't do most of those things with my other hand.
Left: Write, eat, brush teeth, scissors, chop vegetables, etc. Basically fine motor skills on the left. Right: Throw a baseball, shoot a basketball, play tennis, etc. Power movements on the right. Could always do some sports lefty, like switch hit in baseball, kick a football (soccer) past half field, or play pool, those kinds of things, but right side has always been stronger. The only sport where I am much better l…
I cannot imagine trying to throw a baseball with my left hand, but maybe I should do it anyway.

Left-handed screwdrivers are not real, but left-handed scissors are real. Left-handed watches are also real, the crown is on the left side: https://www.fratellowatches.com/help-my-son-is-a-lefty-a-loo...
Wait do people wear their watch on their dominant hand? I can’t do that, need to use that hand to manipulate the watch. Maybe because it’s a smartwatch.
(Personally I'm ambidextrous enough to never have felt the need for one.)

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?

[1] Unless they are a high-end pen with a nub, rather than just a ballpoint. A pen with a nub may have left-handed or right-handed versions of the nub.

We've got veins returning blood to the heart on both sides of our body, and it all has to go via the circulatory system - not as-the-crow-flies from any point directly to the heart. In any case, even if there was (seems not) a few seconds delay in terms of how quickly poison from a snake bite on one side of body vs other got to the heart, that's not going to make any difference to survivability. It seems that develop…
I would say that brain asymmetry probably is not the cause of hand and leg asymmetry. It has to do either with venomous [1] plants and animals or with muscle use and fatigue. When the hand is stung or burned it performs a quick centrifugal movement instinctively. Then many mammals can suck some blood out with their mouths. That minimizes the venom in circulation, and some additional time to get to the heart might be…
So many left-handers here that feel disadvantaged in our right-handed society. If you ever want to do one thing where you feel you left-handedness gives you an advantage, pick up Kendo (the Japanese swordfighting). You have to wield your sword like everybody else but the aiming is done with your left while the right just provides the power for the stroke (the katana is a two-handed weapon). Since you are not supposed…
> You have to wield your sword like everybody else
This right here is why.
was right handed for 20 years, got paralyzed, became left handed. of course relative to the physical therapy/rehab that was easy -- but it still surprised me how quickly it became fluent. it kind of made me think that it's more just a coin-flip as to which you are, and the conveniences available during critical learning moments early in life. if my favorite rattle or play-thing was placed on my left versus my right i…
But that wouldn't explain why most people are right handed, would it?

Unless you really can switch hands at the drop of a hat (which is incredibly rare), the term is cross-dominant or mixed-handed. I prefer my right hand for fine motor skills and left for gross. I have a coworker is who is almost exactly the opposite.
Exactly, ambidextrous people are freaks of nature, like a professional baseball player who can pitch with either hand from inning to inning, and even then there will be a stronger side -- in other words, it is unlikely that a human being could be equally dominant across both hands.
(I do have clear preferences for many other activities, though which activities go left and which right seems pretty arbitrary, and might just be what I got used to instead of actual dominance. Like, I hold my phone on the right hand because it's in the right pocket, but is that a preference, or just avoiding putting the phone in the same pocket as keys/flashlight/etc?)

Your reasoning makes no sense. Using your left hand to crack nuts vs your right hand makes no difference as far as your heart is concerned. If you are working hard enough to increase your metabolic rate, then your heart will be pumping faster in either case. Also, your theory that increased exercise leads to heart attacks is the opposite of reality!
Anyway there are ways to falsify or verify that hypothesis, but it needs some resources, not much but still, it needs time and subjects to test the hypothesis on. So for the foreseeable future, it will stay as it is, a hypothesis.
