Give us your bloody money
Recently my son's mentor, a 6th former soon off to study medicine collapsed and died. Her heart failed on a catastrophic scale and there was nothing anyone could do.
Apparently this is "Sudden Death Syndrome", a condition so poorly understood t hasn't even got a proper name. There's a small charity called CRY (Cardiac Risk in the Young) who are trying to establish screening programs and identify risk factors and so my 12 year old is soon walking a marathon along the Essex way (yes, that a real place) to raise funds for them.
Nothing can be done when this happens, you can do something to help stop it before.
