True stuff, Top LeveL.  Another reminiscence from the former food store cashier: While on shift, I never got used to seeing obesity or what I suspect was (just?) extreme overweight.  As people age, many have real and sometimes unexpected weight gain due--I hunch--to three factors: changes in physical activity level (read: less or none), changes in metabolic rate (read slow) and NOT MUCH change in thirty or forty years of eating habits. That kinda takes care of most people over, say, 50 years of age. Makes Weight Watchers a ...ummm "growth industry." I know whereof I speak!

What stunned me was the number of --ahem--"big" men and women in their late teens and 20s. These used to be the slim-trim years. Unbelievable. 

Yesterday, stopped the car at a crosswalk to allow two slim, svelte teenage girls to cross.  They were coming back from a Tim Horton's "lunch", scarfing doughnuts and carrying big cold drinks. Couldn't help thinking: "See you two in ten years..."
