Portion sizes have been quickly enlarged over the last twenty years. Just google what a serving of french fries was in 1983 vs 2006. Likewise, the huge increase in high calorie drinks and I'm not just talking about carbonated beverages, but the high-energy and smoothy drinks that come across as "healthy".
Add to that our "time saving" devices (garage door openers, remote controls (for EVERYTHING!), light vacuume cleaners (We wouldn't want to actually work at our housework!), dishwashers, clothes dryers, automatic sprinkler systems etc. etc.
Then, we drive to work, drive to the store, drive our kids to their organized sports and/or play dates, school etc. etc.
I know most of us here try to commute by bike when possible, but for many, unsafe neighborhoods and busy streets mean our kids can't just play outside like we used to do and we can't just walk down to the store or send our kids down when we need a quart of milk or even just get on our bikes and ride to the store without carrying our u-locks and chain cables to keep our bikes safe while we're inside.:(
For most of us...it's been an easing into our current soft life with a slow degeneration of our formerly active, safe and productive lives.
What's the answer:confused:
