Not exactly. Longer life spans are partly attributable to a decrease in cheap to treat conditions such as heart disease*, thus a rise in expensive to cope with conditions such as dementia.
*If you survive you may have a Stent or drug treatment and lifestyle changes - or else it kills you quickly. Dementia patients may require care for years.
