Jogging on the spot is healthy, It not only keeps the body fit, But also freshens up the mind.
Do it many times daily in mindful recurrent breaks of 2-3 minutes apart from short sittings of 50 minutes of studies.
Readers that have upcoming exams are just suggested to take out a couple of minutes per study hour to jog on the spot in their study room.
No compulsion, just a worthy piece of advice.
Scientific studies have shown that a healthy mind can only reside in healthy body which in turn is obtainable only from a healthy diet free from junk food supplemented by such light physical exercises.
