A participant here just sent me an email … Thought my answer wold be 
appropriate to post.

CLINT>> ...That makes 133 “Getting Started … " presentations given in the past few 
years … and only eight attendees have fallen asleep 

I have never given the exact same presentation twice - even if it is a “return 
visit” to a club. There are 12-15 slides that are audience-specific … plus possibly 
adding newsworthy info. Last night, I added the actual NASA radio call made to 
the ISS this week, advising them that the ISS crew needed to move attached 
“escape” vehicles for safety’s sake due to the Russian debris field …

So, yes: I really DO have 133 saved Keynote files archived!
