手掌脱皮手指干裂
又是一年秋季，有些人手的手掌脱皮，指尖脱皮龟裂且裂口出外翻。
如果只是脱皮其实还好，也就手掌的掌纹变白皮肤犹如枯枝扎人，但是如果指尖脱皮又开裂，就生不如死没，一是痛二是指尖的触觉犹如覆盖了一层502胶水。
我的解决办法是在发现贴创口贴的地方皮肤明显更加湿润和热水泡胀手脚皮肤去角质层想到的，然后跑药店买了几幅医用手套，
在睡前洗涂抹新鲜的肉芦荟（用护手霜或甘油也可以）再戴手套睡觉，反复折腾几天后皮肤就恢复了正常机能。
如果情况严重的建议先去医院断诊。

加班文化
早些年(新千年之前), 一群人下岗创业, 长三角和珠三角蒸蒸日上, 内陆的乡镇企业逐渐因为产业
升级开始没落, 内陆乡镇的人开始外出到沿海打工.
这些人的相同点, 没什么钱/背井离乡.
