Worrying puts a strain on the nervous system and accomplishes nothing useful whatsoever.

I can easily recall numerous occasions in the past 50 years when various people assured me that the World was shortly going to end (sometimes on a specific day even). It never did.

One was a friend I had when I was ten years old. She had heard the World was going to end and was very concerned. I said that if she really believed it, she might as well give me all her toys and stuff, cos she wouldn't be needing them. She refused! Evidently her faith was not rock solid. Well, when the World didn't end she was kind of embarrassed, but glad that at least she hadn't given me all those toys.

Now, imagine the frustration and chagrin of someone who's been telling everyone the World will end at noon on July 30th, so they'd better repent...and then he gets hit by a truck and killed on the afternoon of July 29th...and MISSES the whole thing by a day!!! ARGH! He never even gets to find out if he was right all along...and if so, to say, "See? I told you it was going to end!" to all those people who scoffed at him.
