The dying sooner part isn't true. It's just most equipment is built for right handed people. Like guns. Holding a gun like a lefty would feel comfortable with (on the left side) it's closer to your heart so shooting it puts force on your chest and whatnot. You don't die sooner just because.
Omg this is so true! My dad is left handed. I remember going out to dinner and sitting in a booth was like a strategic thing to make sure he wouldn't bump elbows with anyone. #firstworldproblems :lol:
I can write with both hands but idk which side I use more , Usually whichever is convenient for the spot.
