Pensions vs Obesity

With the new pensions report to be published today to set a new retirement age of 67 I wonder if anyone would point out the possible conflict with another population trend? The belief that the rise in levels of obesity in young people will mean they could die younger than their parents. Though there are sceptics regarding this idea, I only ask because having worked on a WHO-backed programme concerned with young people’s health this concern seems strongly held with dramatic evidence of the rise of obesity in the US:

But maybe that’s part of the calculation for increasing the retirement age, with less young people to support the retired? It would be interesting to know if that was factored in.
