I can turn off my sense of smell now by force of will. I've had a weak sense of smell since 1975.
I didn't know I could turn it off until last Thanksgiving when I buried a pet cat and didn't want to smell death as I put him in his small grave.
The bad thing about this is I couldn't taste anything but the mustard in the deviled eggs and the sage in the dressing.
"Dad is this chicken or turkey?"
"Chicken, can't you taste it?"
"Just warm shapes in my mouth dad."
What a waste of a Thanksgiving meal.
It takes me three days to turn off my sense of smell and I haven't figured how to turn it back on yet. I can taste food again but my sense of smell is almost gone. I fear this mind experiment went too far.
