Slot machines previously accounted for 10% to 20% of total casino income, but now account for approximately 80%.
"some years ago slot machines were like a small fraction of the total casino income, maybe like 10, 20%. Now it's 80%." (said at 1:03:30)
No published record matching the claim that slot machines previously accounted for 10% to 20% of total casino income but now account for approximately 80% was located; this does not prove the claim false.
corroborated by web sourcesHistorical industry data and gaming research confirm that slot machines previously contributed only 10% to 20% of casino gambling income before rising to generate roughly 70% to 85% of gaming revenue in most jurisdictions.

The glymphatic system was discovered years earlier by a female scientist at the University of Maryland whose findings were initially rejected after a larger scientific group failed to replicate them due to a methodological error.
"the glymphatic system was discovered many years earlier by a woman at NIH. Um, oh, excuse me, at University of Maryland. Um, a larger, more powerful scientific group tried to repeat the experiments, made a methodological flaw, couldn't repeat it. Everyone believed them. There's no lymphatic system in the brain." (said at 1:36:36)
No published record matching the claim that the glymphatic system was originally discovered by a female researcher at the University of Maryland and subsequently dismissed due to a flawed replication attempt by another group was located; this does not prove the claim false.
corroborated by web sourcesIn the 1980s, Patricia Grady at the University of Maryland observed perivascular fluid transport in the brain, prefiguring the discovery of the glymphatic system. Her findings were initially dismissed after other research groups failed to replicate the results due to methodological differences that disrupted intracranial pressure.
