My reasons :-
1) less pollution and more "green areas". Punggol, Lim chu kang.
More variety of wildlife. Like the Magpie Robin and Saga trees in
amk ( red beads) cant find now
2) Quiet life less population
3) Weather was more cool. Less global warming. When other developed
nation were facing this problem, Singapore and Asia were still in
their infancy.
4)There was no internet (IRC, porn, blogs ect) and healthy
activities fostered between different groups of people like chai
bird, kopitiam gathering. The pub and discos were for the rich and
wealthy.
5) WWF and Michael jackson were the in-thing. Richard Marx for the
depressed souls.
6) Many of our school vacations were spent travelling to Malaysia
on motorbikes or at East Coast and Sentosa.
