Sir, – Two contrasting thoughts crossed my mind on reading that Mayo has the highest number of centenarians in Ireland ( "Location, location, longevity? Ireland's centenarians mapped", February 11th). The first one centred around all that fresh air and clean west of Ireland living, followed by the more likely explanation, that they're all hanging on until Mayo wins the All-Ireland. – Yours etc,
TOM LAVELLE,
