Is it 100% confirmed that this particular Mark Sanderson is 47 years old?
I hope it's true. Another little tidbit of info to use to try to help JW family/friends open their minds just a little.
When someone makes mention of a new GB member being named, you can say, "Yea, heard about that. Dude is {younger than/about my age/just a little older than} I am. Imagine that. The generation that wouldn't need to worry about college, growing old, or retiring, is now running things at headquarters" and just let that sink in...
