我今年69岁,20多年前我的头发就白了。以前,我每月要染1次发,不仅费钱,而且对身体健康存在隐患(有患皮肤癌的风险)。3年前,我开始坚持每天挠头,不再染发。现在,我头顶的黑发逐渐增多,而且面色红润,步履有力,打麻将、看电视也不用戴老花镜了。今年4月,我与老伴去四川峨眉山旅游,我一口气登上峨眉山顶,毫无疲劳之感。同行游客惊奇地问我:“你的身体这么健壮,有什么养生妙法呀?”我笑着回答说:“常挠头!” I am 69 years old and my hair is white more than 20 years ago. In the past, I had to dye once a month, which was not only costly, but also had potential health risks (the risk of skin cancer). Three years ago, I started scratching my head every day and no longer dyed my hair. Now, I gradually increased the number of dark hair, and ruddy, walking, playing mahjong, watching television do not wear reading glasses. In April this year, I travel with my wife to Mount Emei in Sichuan Province, and I boarded the Emei Peak without feeling of fatigue. Peer travelers surprised to ask me: “Your body is so robust, what health regimen?” I replied with a smile: “often scratching head! ”
