The first things I noticed about Grandfather were his thick, bushy moustache and broad shoulders.
外公给我的第一印象是浓密的胡子, 宽厚的肩膀。

By the mid20s, a man will know his back hair destiny barely there, a few tufts, or full and bushy.
从25岁左右开始, 男士们会发现自己后背的毛发变得浓密。

This would be incredibly painful, actually, and even the hair of a bushy mustache isnt very long, offering little to grip.
这样做一定会出奇地疼, 而且胡子不长很难抓住。
