The definition of infirmity is a weakness or failing. An example of infirmity is when you become unable to hear as you age.
And the definition of an ailment is a bodily or mental disorder or illness.
I believe this is incorrect, as you can see body ailment means more of an illness or mental disorder. As an infirmity is more how your body weakens as you get in older ages.
I hope this helps and it right, maybe try to wait to see if anyone else answers and see what they say too! Good luck. :)
