Secrets of a trim and slender librarian

In an ideal setting, a librarian do not have to mop her floor; never dust her bookshelves; hardly ever lift, carry and shelve books; rarely run around searching for the suddenly invisible book; but since most libraries have few staff, a librarian does all that and so much more besides being the accomplished and unflappable librarian. The process of being accomplished alone burns more calories than anything else.

So a brisk walk at high noon (i swear i see people do this) is not necessary, nor a badminton match in the middle of a blistering afternoon. Depriving oneself of the much needed fats, protein and carbohydrates, etc. is also out of the question.

All in all, librarians have toned muscles and neurons.
