Who's suggesting this? A bit presumptuous to go from tracking "thing that definitely kills people [smoking]" to "things that are bad but not that bad [drinking, unhealthy eating]". Quite the slippery slope that thinking tracking smoking will lead to tracking everything.
Why would you track smoking? Because the company pays more for insurance. So, it makes sense to track other things that are indicators for worse health outcomes, also causing higher insurance payments.
What are you saying here? You've lost me. Seatbelts are good and the laws we have in place are there to keep ignorance about them from spreading (ie. if you've never gotten in an accident, why would you wear a seatbelt?). So I definitely agree that we slipped on this slope for a good reason.
They also passed so that the automakers wouldn't be forced to put airbags into cars.
I was all up with agreeing with you until this point - but I honestly find it quite incredible that there are still people that think seatbelts are a bad thing.
It's an example of one thing being tracked moving down the line to something that the majority of people opposed also being tracked and legislated.
