Why are there horizontal grooves on my nails? Can anyone tell me?

I have the same symptoms. The nutritionist told me that this is a sign of calcium deficiency. Most people are like this, especially those who like to exercise and sweat a lot. The calcium loss in the body will be more than that of ordinary people! This will lead to this phenomenon!

In addition, he suggested that drinking 1L of milk a day is enough for people like me who exercise a lot!

(Treat me as a milk bucket, you can squeeze milk out of me in the future)

ps: I go to the gym every day and do the equipment for an hour and a half

The difference between a turtle and a tortoise

Wangba is a tortoise, or a soft-shell turtle. It is easy to distinguish from a turtle.

Compared to the soft-shelled turtle, the shell of the turtle is softer and flatter than the turtle's shell. The skin on the head is more wrinkled than that of the turtle, and the nose is longer than that of the turtle. The turtle only has nostrils but no protruding nose. . . Basically, that's it. In short, the soft-shelled turtle looks very flat, while the shell of the turtle feels very hard and protruding. .
