手指为什么会有倒刺儿呢？原来一直认为是缺乏维生素，今天算长见识了，手指上的倒刺是指甲周围皮肤缺乏汗腺或者是皮脂腺，导致容易缺水，缺油脂，从而出现角质层的断裂和玻璃继而产生倒刺。这可能是因为洗手太频繁，经常啃手指头或者接触有刺激性的洗涤用品，导致角质层损伤，引起倒刺，和维生素没有任何关系。
Are we all in this together?
Mobile lies in to confront the pandemic and eventually to reconstruct the shattered economic requires not only medical and economic expertise but moral and political renewable. We need to ask a basic question that we have invaded over these last decades. What do we own one another as Citizens?
This corona virus pandemic has suddenly focused forced us to reconsider what social and economic rules matter most.
Many of the essential workers during these crisis are performing jobs that do not require college degree they along with the doctors and nurses, nurses are the ones who are putting their health at risk. So the rest of us can seek refuge refuge from contagion contagion.
Beyond thanking them for their services, we should reconfigure our economic and society too called such workers, the compensation compensation and recognition that reflects the true value of their contributions， Not only in an emergency but in our everyday lives.
Such a reconfiguration requires deliberating as democratic citizens about what can see constitutions a contribution to the common good and how such contributions should be rewarded without assuming assuming that markets can decide these questions on their own.
We need to ask whether reopening the economy means going back to a system that over the past four decades pulled us apart or whether we can emerge from this crisis with an economy that enables us to say and to believe that we are all in this together
