LOL! Naw, now't o' the sort! :)
You can be a combo dosha - any combo is possible. :) And waht you want to do is calculate the test yourself, discount any of the physical appearance questions except for nail and eye diagnoses, and overall build. Hair color, eye color, discount those, see waht you come up with.
You can also read the three descriptions - since there ARE only three heh - and see which one fits you. :)
I'm lucky, I'm VAta all the way, there's no mistaking it. Makes it easier. Combos need to focus on whatever aspect of their multiple doshas are out of balance. Like a pitta/vata person who was always too hot and sweaty would have to follow a pitta-pacifying lifestyle.
Hope that helps!
