aging taste/smell

[Laura L. M. Hoopes]

I would be wuite interested to hear about age-related changes in this
system.  Is the genetic structure of it not a bit similar to that of
the immune system protein genes?  Surely it has to address the sort of
variety recognition issues that imuume system is faced with.  Does taste
reception drop out whole sets of recognitions with age? Or not see new
tastes but only use memory tastes?  What happens?  Laura Hoopes
