I haven't had gum since I was about 11. I wasn't allowed it until as 10. On my 10th birthday I immediately bought some just because I could, went mad on it for a little while, then got mored and didn't bother again. I also got a little scared because of rumours floating around that said gum could give you mouth ulcers.
Back then I could blow bubbles with bubble gum, but not with chewing gum.
i did with bubble gum when I was 12 years age that was the fashion then looks like it still is. never did like chewing gum or bubble gum. only for blowing the bubbles thank goodness I gave it up soon after, I dislike seeing people chewing gum looks a a cow chewing its cud..
