emily: i think it is basically up to how much u believe? IMO, if u believe deeply in FS, then best to follow it, its the same as the pantang issues, if u believe in it, best to follow but if u do not, then not necessary.
for me, im more like 1/2 1/2, some i find logical enough, then i will go ahead and follow. others, i will just let it pass. but also up to your parents, whether they will be particular abt it anot.
