Wow, utmost respect for this lady.
I was amazed several months back when I swam my first mile, only mentioning this because we are the same age................and that's where the similarity ends.
I just came across the following:
"The world still needs people such as Diana Nyad, people who demonstrate the strength of will by taking the impossible and making it possible. Nyad's straits of Florida are a metaphorical stand-in for any number of challenges that people believe they'll never overcome. Her refusal to quit inspires others to press forward. In an era where few mountain summits remained unclimbed, we still need impossible pursuits to reaffirm the indomitability of the human spirit."
