As the New York Marathon went underway, I am reminded of our much respected professor in medicine, Old Mac.
“It took 5 minutes to drown and 20 days to die from dehydration.”
It is amazing that after over 40 years they are just beginning to realise that. Research on Marathon runners showed that many had low sodium, a sure sign of over-hydration.
