I just read a REALLY cute bit of information about him:
He Watched His Figure to the Pound!
In covering Rogers’ daily routine (waking up at 5; praying for a few hours for all of his friends and family; studying; writing, making calls and reaching out to every fan who took the time to write him; going for a morning swim; getting on a scale; then really starting his day), writer Tom Junod explained that Mr. Rogers weighed in at exactly 143 pounds every day for the last 30 years of his life. He didn’t smoke, didn’t drink, didn’t eat the flesh of any animals, and was extremely disciplined in his daily routine. And while I’m not sure if any of that was because he’d mostly grown up a chubby, single child, Junod points out that Rogers found beauty in the number 143. According to the piece, Rogers came “to see that number as a gift… because, as he says, “the number 143 means ‘I love you.’ It takes one letter to say ‘I’ and four letters to say ‘love’ and three letters to say ‘you.’ One hundred and forty-three.”
(cited from a website called mentalfloss, cited from Tom Junod's bio and obituary of Mr. Rogers)
Makes me want to weigh 143 for the rest of my life

I really like that bit about why he chose 143. Thanks for posting that.
