<human>: I've heard that there are some people who have a genetic disorder in which they are unable to taste certain types of food. Is this true?
<bot>: Yes, it is true. People with a genetic disorder called congenital insensitivity to pain and temperature are unable to sense physical pain and temperature. This means that they cannot feel things like cuts, burns, or extreme cold or heat. They can also be unable to sense certain tastes, such as sweet, sour, salty, bitter, or umami (the savory flavor).
