Two days ago I had a medical check-up.  My blood sample was taken and the lab results showed
that my sugar level, cholesterol level are all OK.  My blood pressure is also OK.  I am glad and
happy with this.  My routine walk/jog for 5 km every morning, followed by barbells and dumbells in
the house, including sit-ups, squats, waist twists and culminating in shadow boxing and fencing helps
to maintain good physical fitness.
Yes, one must work hard to have good health.  You must work the muscles, the heart and lungs -
and when you inhale a lot of oxygen you really feel good.  I believe that a lot of human ailments
are due to physical inactivity. And its a misconception that by taking pills you can be healthy.
