I’ve mentioned, once or twice, that I’m now 83 – quite a long life, so far, really. If I, in April 2043, could send myself a sentence, it would be, “You made it!” Or rather, “I made it!”

I suppose a message from 2033 could say! “Hey, I got this far!”

A message from 2027 could say, “So far, so good!”

But, if I received any one of those messages, it might make me think, “Well, I don’t need to take care crossing the road any longer,” or “Now I can stop taking my blood pressure meds or statins!”

Then, maybe, the message I received might just disappear! Oh, no!
