Government makes money out of pensioners, both in life & in death. Your pension is taxed. Lump sum payouts are taxed (after a certain amount). In death, your estate is taxed. 
Beside all the above, a pensioner still pays taxes on water, electricity & rates. 
A pensioner also pays VAT.
With all the taxes & expenses many pensioner have, I doubt that many pensions can live a stress free life.
Our entire system of taxes & retirement need to be transformed. Pensioners have paid their dues to society & need to be treated with respect & dignity.
Our Government simply sees pensioners as another source of revenue.
