"It turns out that there is a lethal dose of caffeine," Mitchell Moffitt, co-creator of the ASAPScience YouTube series, says in the video, "which is somewhere around 150 milligrams of caffeine per kilogram of your body."
That's a lot of joe. If you weigh 154 pounds, Moffitt explains, you would need to drink about 70 cups of coffee at once to fatally overdose. Although the number could vary depending on the kind of coffee you prefer and how it's made, that's one beverage binge that even the most compulsive java junkie would be hard-pressed to pull off.
"You wouldn't be able to physically fit that much in your stomach," Moffitt says. "You would also start experiencing mania and hallucinations before getting to this point."
Good to know.
