That's an easy one....
Government (over)regulation.
There seems to be a law against everything these days.
Our freedom is truly being diminished.
In the old days in the 1980's we drove fast cars very fast, we ate fast food even faster, we had competitions who could use the most amount of fuel (petrol), we could buy lot's of firecrackers, sky rockets, parachutes, and bungers, thunders, and had big bon fires on the Queens birthday Sunday night which we really looked forward to each year, we got sunburnt (to a crisp)(regularly) and would have fun peeling the blisterd skin off a few days later, we could run a hose day and night and waste lot's of water, we had fun "going for a drive around the block" (from western Sydney to Newcastle then south over the Sydney Harbour Bridge to Woolongong and back home), a few times we drove from home (in western Sydney) to Melbourne just to buy a hamburger and chips, then turn around and drive home, police were often considered approachable and called friends, McDonalds was healthy food, beer was considered water (hence healthy), sun tans were considered healthy (especially if you used tanning oils to darken your tan even further), you could road test the latest mods to your RS2000 by cruising the F4 (now the M4 Motorway in western Sydney) at +220kmph at 3am on a cold winters morning with Deep Purple's Smoke on the Water playing at full volume, you could go to disco's and there was no fear of drugs or being drugged or bashed, fights were played by the rules and were a fair competition, petrol had lead in it, there was only leaded CocaCola (no diet Coke), AIDS had not been invented, mobile phones had not been *invented, hell the fax machine had not been *invented! (*really not released enmasse), country roads still had windy bends in them (not boring freeways), you could leave your front and back doors open and unlocked while you were asleep or up at the shop, a gaytime was a paddle pop covered with bread crumbs, a cherry ripe tasted like one, there was no such things as carjackings, or home invasions, music had meaning and had a story, you could take your car to the local mechanic to fix (not forced to the dealer), the nice man would come and fill you petrol tank with fuel while you watched (before self serve) and he would check your oil and water if you asked, to get my motor bike licence I was simply told by the country policemen to go the the post office and pick up the police mail for the day, to get my car licence I was told to take the police paper waste bin to the local tip (on each occasion the licence was typed and prepped ready for me when I returned - no questions, people would always say hello, people were usually very happy and sincere, meat pies had meat in them, television was actually entertaining and very little violence, Australia actually made things - no such thing as Made In China, Made in Japan was considered "Jap Junk", Made in Taiwan had not yet been invented, most engines had eight cylinders, most cars were made in Australia by Australians, the Hardie Ferrodo Bathurst Car race was entertaining, food had flavour and only a few preservatives, everyone had a job, if he didn't like that job he would leave and start another a few days later just down the road, a speed camera was something you took photos of trees with while cruising at 100 mph....
And guess what, despite all the things we did, we did live through it all. Always the wiser with more knowledge for the experience, and we managed rarely to hurt ourselves, and we never hurt anyone else.
