In my grandfather's time, I was just a teenager, and my head was always running around. Teenagers aged 15 or 16 are almost 1.6 to 1.7. Grandpa was anxious and said to press me with a stone mill. Hey! That's not bad The next day, grandpa said, change your fitness. I'm curious too. What fitness programs does grandpa have? Friend, guess what it is? It turns out that good people carry big shit, which is a good way to inherit ancient oppression in rural areas.
