While we're on the "when I was young ..." wagon, we didn't even HAVE TV in South Africa until 1976, (censorship) and then it was the snow pattern until 6pm, when the news came on. We were allowed to watch the early news, and whatever came after it, and that was it. Dinner was eaten together at the table, as was Sunday lunch. My brother had food allergies, so my mom didn't buy anything with sugar, preservatives, colourants or other additives.
MacDonald's etc. didn't enter the market until a few years ago, and although there were other fast food outlets, they were only for rare occasions.
Even proper restaurants aren't that healthy. I was horrified when I went to a full-on sit-down restaurant in America last year and ordered a vegetarian burger and salad. They gave me one of those frozen Garden Burger things and a heap of iceberg lettuce (with supermarket dressing)! I could have made that at home for a tenth of the price, and it would have been tastier and healthier. Lessons learned.
When we weren't at swimming training or music lessons, we'd be outside playing on our bikes, skateboards or rollerskates (perfect weather year-round).
It's different now - people are afraid to go out on foot, fast food and convenience food is all over the place. People are busier, somehow. Basically, if you don't commit to getting in shape and staying that way, it's a lost cause.
Living in Japan, it's always culture shock to go home or to the States. People here are, on the whole, quite slim, if not downright skinny. Everyone in cities has to walk at least 40 minutes or so per day, getting to the station and to work and back. And the food's generally healthier, although increasingly people are eating fast food and convenience food. Apparently young people here are also getting fatter - they just play TV games when they're not at school.
So - let's get out there and kick butt! When people give you shit and say you're obsessed, look them in the eye and ask them if they ENJOY the way they look and feel, if they're comfortable with it. Show them how small, easy changes can affect their health and appearance. Educate them on nutrition labels and what they mean. People like us can help to create a new "oral history". Right?
