Agreed with that. Gotta start thinking somewhere.
It’s just bad to assume and answer as fact with only that behind the answer. If you do, it should be stated as something like, “It’s theoretically —-“ or I’m thinking theoretically —— I normally say “*I Think*” and I’ll say my close friend did this, and bet you bottom dollar it’s a fact. But not use or answer something with “Some guy at the track….” Or other non reliable source.
