Weird Facts About Your Body
The human body is full of strange and fascinating surprises. For example, your stomach gets a new lining every few days to protect itself from being digested by its own acid. You also produce enough saliva in your lifetime to fill several swimming pools, even though you rarely notice it. Even your skin is constantly changing, as old cells fall off and are replaced by new ones all the time.Your body can also react in unexpected ways. Goosebumps appear when tiny muscles pull your hair upright, a reaction left over from ancestors who needed to stay warm or look bigger to scare predators. Hiccups, sneezes, and sudden muscle twitches may seem random, but they are all part of your body’s complex control system. These odd facts show just how amazing and mysterious the human body really is. Shutdown123
