Lol, I think it's quite possible to look back at a decade you weren't born in and see the best parts of it.
Not a bad decade at all as it goes. The plus points outweigh the negative ones. The music, the drugs, the moonlanding, the drugs, free love (man), the drugs, the 66 World Cup and the drugs far outweigh the Vietnam War, Cuban Missile Crisis, gangland wars in London and Manchester. Not many other bad points I can think of tbh...although my brother was born in 68 so that's a major negative point.
