Halloween is the time when the sweet tooth deep inside me takes control and causes me to make irrational decisions, like the one to eat most of the chocolate Halloween candy before the kids even knock on my door. Sometimes I really hate my sweet tooth, you know? But according to a Finnish study, a sweet tooth might be inherited -- that is, it's in your genes. In fact, there's even a specific chromosome variation linked to a love of sweets, and those who have it find sweet-tasting stuff much more pleasant than those who don't.

Makes sense to me -- my dad was a lover of sweets too so I know where I got it from anyway. But, does this mean that it's something I can't change? What do you think?
