@4:40 - RE: Food as Reward = Business as Usual (BAS). Any food that triggers some feel good chemicals can be abused: junk food, fast food, processed food, alcohol, tobacco, drugs. Some are legal others carry a stigma and others are illegal ... depending where you live. (Liberal) Progressive policy making would be to legalise all but put a progressive and aggressive tax on those. An addiction & harm tax along the nudge theory. And with that tax revenue to pay for public health care and public education campaigns to raise awareness and change perception, image and opinion. Not pulling the nanny state. But if you use tobacco, you pay twice; now with your discretionary spending choice and then with your health, and we let you know on the packaging. And we can also subsidise cycle to work schemes, cycle lanes, cycle shelters.
