You will smell things that can only be described as hellish.
Very first patient I got to deal with when doing my clinical shift in the ER was a 97 year old woman who had a hemorrhagic stroke and was pretty much comatose (and she was definitely dying). We went to take her temperature rectally and the diarrhea started. Luckily while I was holding her so the nurse could wipe her, she began throwing up so I got to hold a bowl for her to vomit into. It was kinda like jumping right into a cold pool, taught me that no matter how horrible the smell, I could deal with it.
Though sometimes the smell randomly comes back to me.
