Whenever I get medical procedures done I imagine someone from the past watching it and I was like man someone from the 1500s would find blood draws so weird but THEN I remembered the four Humors ans blood letting and I was like actually they'd find the whole bleeding you bit par for the course,
They'd just think it was weird we were gonna Do something with the blood afterward
Me, a time traveling doctor, handing the blood samples off to my nurse: okay you're good to go
My patient: wait...what's she doing with the blood
Me: ah uh, gonna. Pour it over her garden to make her veggies come in better this year
Patient: oh of course cool thanks *leaves*
Nurse: but we are checking it for sy-
Me: syphilis yeah
