[Tugindia] Stopping hyphenation

[H S Rai]

Is  there any  way  to  stop hyphenation  in  whole document. Is  that
advisable?

Or any  simple way to  avoid hyphenation in section  and subsection. I
find for  most of  sections, only  "half word" is  there in  2nd line,
which looks  bad (though I  believe LaTeX do,  what is good)  to many.
They say hyphenation  may work fine for paragraph, but  in section etc
it does not give good appeal. What's your view?
