The San Francisco bridge was constructed in record time. In that era it was expected that one construction worker would die for every million dollars spent on the building of a bridge. It cost 27 million dollars to build but there were very few lives lost.
Why was the bridge able to be built quickly and with less loss of life? Because they put a net under the bridge to catch anyone who fell. Normally the workers had to wear restrctive safety lines but with the net they were able to move about freely without ropes. The net saved 19 lives.
We have a net too. We have security that the world dosn't have. If we are in trouble we have protection, that gives us the freedom to move about in this world with confidence.
