So in conclusion, present-day Londoners are lazy, and rather than encouraging people to move more, we should pander to them. Why not give everyone a Coke and a Big Mac with every Oyster card too? No wonder there is an obesity crisis.
I watched someone carry a wheelchair down the escalator a few weeks ago. No one could get past them, since the owner of the wheelchair was clinging to the person kind enough to escort them.
That short escalator ride isn't a public health disaster.
The lack of healthy food available to commuters is probably a bigger problem.
Recall how much the idea of evolution bothers some people. Are you sure this isn't a similar type of situation?
We seem to have evidence that obesity isn't always a choice.
