can anyone else do this?!
Answers:
Some people's tolerance for taste and heat is very different from others. My father is like yours, and can eat exceptionally hot foods without thinking twice. Funnily enough, my sister is very sensitive to spices and chilis etc, whilst I'm the kind of guy who needs tabasco sauce on everything to be able to taste it.
You might find your father is very sensitive to sour foods, or a different type of taste.
Have him try a fresh ghost chili. I bet he wont eat those like candy!

I guess your dad is used to spicy food.
If you want to eat spicy food I guess you should avoid it touching your tongue.
