Please remember what these organs are afraid of.

Kidney:
Afraid to stay up all night.
Stomach:
Afraid of cold food.
Lungs:
Afraid of smoke.
Liver:
Afraid of fatty stuff.
Heart:
Afraid of salty food.
Pancreas:
Afraid of over-eating.
Intestines:
Afraid of eating non-veg food indiscriminately.
Eyes:
Afraid of mobile and computer screens.
Gall bladder:

So, please take really good care of yourself because spare parts may not fit; they are very expensive--and not necessarily available in stock!
