We can get to talk with any of them… like, it is a time machine to transport us into times when they were 5yo at their times? None said what age these persons would be.

Or maybe it is more like necromancy? yes please!

Tesla, to check on many mysteries (totally not to get actual death ray).

Or maybe Skłodowska-Curie, to get self radiated.

Or Bphr, for beer.

None said these 3 hours are for free. Actual therapist may still be cheaper ;c
