Madam, – Any increase in pension age is not “heartless” as some TDs are reported to have said (Dáil Sketch June 16th), especially if the increase is to some extent “optional”, as deputy Joan Collins is reported to recommend. The fact is that, because we are blessed with long life, the cake is not large enough to go round unless those who are fit and healthy are allowed to choose to postpone their own retirement age. – Yours, etc,
