(Original from internet)
* Have a look at your wastes
Wastes should, like the intestines, appear S-shaped and smooth; if appearing marble-like blocks, you are suffering from constipation. Eat plenty of high fiber foods, and drink plenty of water.
* 观察一下你的排泄物
排泄物应该和肠子一样呈S形,并且非常光滑,如果呈块状像大理石一样,这说明你有便秘。多吃一些高纤维食物,多喝水。
