Obesity in all its manifestations is directly linked to worker productivity and has multiple causes the main one of which is excessive eating and drinking of the wrong things coupled with a sedentary lifestyle.
It should, as Dr Alf suggests, become a top priority with the tax system, and heavy pressure applied to the obese,food and drink manufacturers and the makers of plastics to change their ways.

As it is, the only thing that is happening is a steady 5% growth in the number of mobility scooters sold to people so bloated and enormous that they cannot walk.
Ex-military personnel and people injured in road accidents should get mobility scooters but the rest need to be encouraged to exercise, eat sensibly and stop drinking on an empty stomach.
