主题：How often do you get sick?

I used to get sick 2 or more times a year but then I started eating really healthy, lots of veg, whole grains, fruits, nuts and seeds, meat, no junk food and very few empty-calorie food, and I haven't got sick this year at all. My immune system is badass now.

Whole grains: 全谷物
Empty calorie: 空卡，没有营养价值的热量

Badass：（俚语）吊炸天
