If you look after your body and health the best way you can. Dont smoke, dont eat rubbish food, do some exercise etc, then when something bad does happen to you - you will have a fighting chance of surviving it.
Think of all the NHS hours saved - that could then be used on people who have had an accident, genetic disease, OAP's etc.
ps - dont forget to tax all the food manufacturers adding sugar to their products - to cover the cost of the damage people are doing to their bodies.
