Reflections on Jaws.

It's seriously hot here in Byron Bay at the moment, which makes our daily Cape Byron walk all the more enjoyable when we incorporate a swim at Wategoes' Beach afterwards. 

This morning as we approached the surf, Cassie asked me a question.
"What causes fish to leap out of the water?"
"Something chasing them usually.." I replied. "a shark perhaps."

Cassie contemplated the answer for a minute and continued walking into the surf. She halted with the water about two foot deep.
"Are you calculating the risk of going deeper?' I asked.
"Well he might not be able to attack so easily if it's shallower..: she replied. "And the water is luscious!'

Which got me thinking about how we assess danger. She saw immediate danger. And she began calculating the odds of getting torn from limb to limb.. and decided that by remaining in shallower water, the perceived benefits of a dip in the ocean was worth the fear of a serious shredding.

How do we work out our risks of a painful old age? Or do we even bother?
It's obvious that a painful old age will happen if we continually swim in the deep water of bad diet and minimal exercise, and the pain could be far worse and old longer duration than a quick leg off from a Noah's Ark.
