ELI5: Why do my fingernails need trimming much more frequently than my toenails, do they really grow like 5 times faster?

They do grow much faster. A lost fingernail will grow back in about 4-6 months while a toenail will take up to a year and a half to grow back. As for why, no one's 100% sure, but it's believed to be due to greater usage of fingernails (more wear and tear) and the hands being closer to the heart (more nutrients).
