How did we survive?

Reading the latest posts about the way we were, got me thinking about my younger days, in the late 40's. Anti smoking legislation? The barber who cut my hair when I was a lad, would have laughed at such a nonsense. He was never without a cigarette in his mouth, as he never put it down. He would circle his customer, snipping away, and blowing clouds of smoke over the persons head. He had a son who was about to leave school, so he was being taught the 'trade'. Who better to practice on but a young lad (me). He was so inept, that he gashed my kneck with the hand clippers.He puffed half a can of powder to try and stop the flow of blood, and topped it off with a fag paper. He then took my money, gave me another fag paper, and opened the door for me to leave. 
What would Health and Safety have to say about the local butchers shop? Unrefrigerated meat on display. The floor covered in saw dust to dry up the blood. Although I cannot ever remember seeing the outside of the shop covered with various cuts of meat etc., I do remember the outside of the shop being covered with the bodies of dead rabbits, with flies buzzing round them. They were gutted, but still needed to be skinned. As meat was on the ration then, I suppose this was an alternative for some people. My Mother refused to buy any rabbit. She 'would rather go hungry'.
What about the Bakers shop? How many people must have handled the uncut loaves before they arrived home? All cakes and doughnuts were picked up with bare handsup by the staff and dropped into bags.
In the Grocery if you wanted ham or corned beef, it was picked up and placed on the slicing machine, and each slice was handled as it was placed onto grease proof paper.
