One more thing I wanted to add was soda - how machines are popping up everywhere...I think my high school got its first soda machine in my senior year in '82.
And how much the soda aisle has grown as well...growing up my favorite soda was club soda for some reason and I am glad I developed a taste for it early on!!!! No carbs!
When I visited my relatives in TN recently I was appalled at how much soda they drank - ughhhhhhh! (and yeah all but 2 of them are overweight, including the kids).
My kids prefer water - milk - juice in that order. Occasionally I allow them some seltzer or some splenda-sweetened soda but that's it! Generally if you ask my girls what they want to drink they will say water first...
