A closer look
Fingernails on your dominant hand grow noticeably faster than the ones on your non-dominant hand simply because increased daily usage stimulates greater blood flow and nutrient delivery to those specific fingertips. Constant tapping, gripping, and aggressive keyboard smashing actively feeds the nail matrix, resulting in a completely asymmetrical growth rate that nobody ever really notices until it is pointed out. It is a tiny, annoying biological reward for being right-handed in a world specifically designed for right-handed people. This fun little physiological quirk means you are constantly wasting microscopic amounts of keratin and vital body energy strictly on the side of your body that does all the heavy lifting. You are effectively growing tiny, useless fingernail extensions at an accelerated pace just to ensure you have to hunt down the nail clippers slightly more often than you realistically should
