Spare a thought for 62 year old Diana Nyad who has had to give up on not one but two attempts to try and swim from Cuba to Florida. On the first occasion she suffered an asthma attack and then on the second try she received a nasty sting from a man-o-war jellyfish. She had swum about 49 miles of the 103 mile journey.
One of Diana's primary aims was to try and inspire people to remain active as they age.
They do say that if at first you don't succeed then try again. If that fails even more spectacularly then it is probably time for a cup of tea and a revisit of your goals!
