Hmm everyone seems to be so fascinated about what would have happened if...but it didn't happen, you know? Hitler did live and do all those terrible things and JFK did die, perhaps unfairly.
These are things you can't change, or at least that's what I think, and so I wouldn't want to go back and change things. But like many, despite all the bravery about not being able to change things, I do have a few moments in the faraway past I wish I could change.
As for visitation? Too many to mention, although to many I would only go as a visitor. Awesome though they might be, they had some funny rules.
Have you read 11.22.63? It's by Stephen King, back when he still wrote good books. :) you might like it!

I like this post and very much the idea behind it! I do hope I am on that list of saved people :P And I must say, I've never been called venerable before. :))
