Fred99: When I was a kid, we used to play on our garage roof, but the time we were about 10, we could safely jump off it onto the ground.
If the namby-pambies managed to be persuaded by vested interests of the roofing industry association that you're not allowed to go on to your own roof, I'll simply disobey that law.
NZ is going nuts - if the safety/building consent laws we have now had been in place in the 1850s, then we'd all be living in tents.
Like the Wellington guy who refused to comply with the Bicycle helmit laws citing reasons similar to your statement. He was killed when he had an accident on his bike, cause of death.... Head injury.
