Fast food is popular because... it's fast.
Could you get something healthier - for the same price - and get it just as quickly?
Here Is Your Challenge
From your place of work (or wherever you are during the day).
1. Put your stopwatch / timer on.
2. Get yourself down to the nearest deli or grocery store (generally the smaller ones mean a quicker shopping experience).
3. Order some real food (i.e. some fruit, maybe something nice like roasted nuts, and perhaps some protein - like slices of turkey breast, or some smoked chicken).
4. When you have the food in your hot little hands - stop the watch and note the time.
5. Take note of the cost.
Now we need a control... You'll have to repeat the same experiment with a fast food joint (all in the interest of science of course). Although I cringe at the thought of a burger and fries -- someone out there must be willing to do the whole experiment. Someone? Anyone?
