I think doing sabbatical is good for people. I have never been doing that before. Many articles mentioned that sabbatical is good for our health, mental, and mind. This is some articles that I would recommend to read:
1. This is what 365 days without a vacation does to your health http://qz.com/485226/this-is-what-365-days-without-a-vacatio...
2. The 2015 Sabbatical: Why We Should All Take a Month Off - https://www.riskology.co/sabbatical/
By the way, thank you for making this post. It reminds me that I have to take a month off because of my works.
