She has donated her kidney, eggs, part of her liver and now offers her lung

But following the operation Mr Rosenfield is now 73 and living an active life.

After hearing about the generous kidney donation, a childless couple in Australia got hold of Mrs Gianstefani to ask if she would consider donating some eggs to them for IVF treatment.

She donated 27 eggs, and managed to find out that three had been fertilised before losing touch with the couple.

To this day she has no idea if the pair ever managed to have children using her eggs.

Mrs Gianstefani was forced to go abroad to make all of her donations as altruistic donation was illegal in the UK until 2006 amid fears that people could be coerced into giving.
