“Mae’n hawdd rhoi gwaed – rydych chi’n cael dishgled o de a bisged yn wobr – a gallai eich ymdrechion chi fod yn achos o fyw neu farw i fam, mab, nain neu ffrind.”
“It’s easy to do – you get a cup of tea and a biscuit as a reward - and your efforts could literally mean life over death for a mum, son, grandma or friend.”
