I feel insanely dumb for not saving a screenshot. Here are some details for anyone who has had the same ad.

I was watching a video by videogamedunkey. (Advertised to a more gamer demographic I would assume). Only other channel I watch to a high degree is penguinz0.

There is only one image of a plague doctor on the left side on the screen facing the right side.

Not word for word but two general point of interest I remember. ‘I’m just a regular guy I have a wife and kids, ect’. ‘I have some interesting thoughts I’d like to share’.

Voice is male and has a soothing speaking tempo at around 70 bpm.

This is a long shot but if anyone can help me, thank you.
