Yep! Go for it!
This is a question that most of us come across, especially those who do not have any medico in their family.
We hear about some random guy who cleared neet who used to study for 15–16 hours a day or even more…We are made to focus on quantity of hours we study rather than the quality time we give to our books and this concept is as wrong as anything can be.
Nobody can study continuously for hours put together and it’s not even needed…We all need breaks and should take them whenever we feel like…And persuing your hobbies in that time will be its best utilisation:)
