My sense of smell is only good for bad things, as I have a partially blocked nasal cavity. My sight is good to a point, but being slightly cross-eyed, long-sighted with astigmatism, it ain't gonna be perfect. Hearing is sensitive, and is mostly affected by music. Hearing certain tunes from faraway or in the background is a speciality. I used to be really good at spotting if someone was gay, but that has worn off over time. John Glover, who plays Lionel Luthor in Smallville is gay, and I never noticed. Yet (before it was a media thing to out yourself or someone else) I was always able to tell. Weakest sense has to be common sense. Knowing what the right thing to do is bypasses me for a pastime.
