Never play with penalties unless you are convinced you understand how 
they work.  It is all laid out in the TeXbook, but it is not a simple 
matter, and penalties interact with one another.  Simple, one-off 
changes, like the ones associated with Plain TeX \break, are OK, and all 
the more so when it is Don Knuth who set them up, but otherwise, a 
general policy of hands off for penalties is a good idea. 

\lefthyphenmin=1000 is a simple, transparent integer.  It does not 
interact with anything but the hyphenation pass, and it simply makes it 
impossible to hyphenate any word imaginable.  It is not originally my 
idea, and I wish I could remember the name of the unsung genius who 
thought of it.
