I have a document with ONE space after each sentence. I would like to use
"Find and Replace" to change the single space to TWO spaces.

This is an easy problem for a human brain, but I'm not sure how to get
everything I want (and Not get what I DON'T want) with "Find and Replace".

Example BEFO
Sentence one. The second sentence. Here's the third. And finally the last.

Example AFTER:
Sentence one. The second sentence. Here's the third. And finally the
last.

Is there an easy way to do this? My document is over 60 pages long.

Thanks!
