In my never-ending quest to be as confounding as possible I have developed the need to have that most famous Vulcan greeting "Live long, and prosper" translated into Scots Gaelic.

Several online sources actually have this exact phrase (I guess by now it is a pretty universally understood phrase...Trekkies reproduce, after all.)

Sonas 'is fad saoghail leibh


Just checking to see if anyone cares to either agree with or dispute this translation.
Thanks!
