Walking on the sunny side of the street is being recommended for teenagers because they spend so little time outside that they risk developing rickets.
Adolescents who spend most of their time inside, in the shade or in cars, have so little exposure to sunshine that they risk becoming deficient in vitamin D, which is important for bone health.
But concerns about "stranger danger" mean that modern children spend many more hours indoors than their parents.
I have a theory that there is an optimum number of broken arms in children - too many and the place is stupidly dangerous, too few and kids are being mollycoddled too much. Apart from a Fairgroung Chav I haven't seen a kid with his arm in a sling for a long time..

I'll never forget that first day at t'pit.
Me an' mi father worked a 72 hour shift, then wi walked home 43 mile through t'snow in us bare feet, huddled inside us clothes med out o' old sacks.
Eventually we trudged over t'hill until wi could see t'street light twinklin' in our village.
Mi father smiled down at mi through t'icicles hangin' off his nose. "Nearly home now lad", he said.
We stumbled into t'house and stood there freezin' cold and tired out, shiverin' and miserable, in front o' t' meagre fire.
Any road, mi mam says "Cheer up, lads. I've got you some nice brown bread and butter for yer tea."
Ee, mi father went crackers. He reached out and gently pulled mi mam towards 'im by t'throat. "You big fat, idle ugly wart", he said. "You gret useless spawny-eyed parrot-faced wazzock." ('E had a way wi words, mi father. He'd bin to college, y'know). "You've been out playin' bingo all afternoon instead o' gettin' some proper snap ready for me an' this lad", he explained to mi poor, little, purple-faced mam.
Then turnin' to me he said "Arthur", (He could never remember mi name), "here's half a crown. Nip down to t'chip 'oyl an' get us a nice piece o' 'addock for us tea. Man cannot live by bread alone."
He were a reyt tater, mi father.
He said as 'ow workin' folk should have some dignity an' pride an' self respect, an' as 'ow they should come home to summat warm an' cheerful.
An' then he threw mi mam on t'fire.
We didn't 'ave no tellies or shoes or bedclothes.
We med us own fun in them days.
Do you know, when I were a lad you could get a tram down into t'town, buy three new suits an' an ovvercoat, four pair o' good boots, go an' see George Formby at t'Palace Theatre, get blind drunk, 'ave some steak an' chips, bunch o' bananas an' three stone o' monkey nuts an' still 'ave change out of a farthing.
We'd lots o' things in them days they 'aven't got today - rickets, diptheria, Hitler and my, we did look well goin' to school wi' no backside in us trousers an' all us little 'eads painted purple because we 'ad ringworm.
They don't know they're born today!!!
