Subject: Importance of Physical exercise
Dear Sumon,
Take my love.
It's not pleasant to know that you're suffering from continuous ill health. I guess it is happening because you're not serious about regular physical exercise. To keep sound health we should do regular physical exercise. It keeps our body and mind fresh. It also enhances our physical immunity. Any sorts of sports, running, swimming, walking regularly can be good physical exercise. So I will have a request for you. When you'll recover, please do regular physical exercise.
Wish your speedy recovery.
Tamjid
