As children we would walk to school , play outside till it was dark , junk food wasnt around till I was about 11 & that was KFC, We only had that maybe twice a year !
Now children are driven to school then sit inside and play on their computer/phone , watch tv etc . I did a hub on this .
even tho we now have mod cons everyone is always in a rush so take the car instead of walking or cycling .
If you look at the average( NOT ALL) big persons trolley it is full of junk food , fizzy drink etc ,
The average slim person has more fruit, vegies etc in theirs .......
Some do have health problems and just cannot help it.
