With the advancement in technology, the world is moving at a faster pace than ever before. People are doing more things and juggling between different activities, leaving them with little leisure time. Some people believe that during this time, activities that involve mind work should be done, however others are of the opinion that one must relax and keep mind at peace during leisure time.
Doing less of any activity during leisure time makes sense to many for different reasons. Firstly, after working for so many hours or days, one needs some time to relax. For instance, a person who is may be working ten hours a day, during his/her rest time, prefers either to go to movie or massage, so as to boost energy for the next day. Secondly, everyone has their own choices and priorities. Like, a doctor who is already tired of working throughout the day might not prefer a five kilometers run.
However, doing mind work during leisure time is an effective way of relaxing for those who are involved mostly in physical work. For example, a footballer who is most of the time either practicing football or playing a game, might prefer reading a book during the leisure time.
Overall, in my opinion, what a person chooses to do depends entirely on the kind of work they do otherwise. Although reading or doing mind activity is right for some, others can very rightly prefer another activity.
