The earliest fossil evidence for anatomically modern Homo sapiens dates back 300,000 years.
Do you think your ancestors cared about eating, drinking, and sleeping schedules? Or, is it more likely they ate when hungry, drank when thirsty, and slept when tired?
Your ancestors might agree on the benefits of drinking water, but they’d also agree about the lack of scientific evidence to drink an arbitrary number of glasses of water every day.
Drink 8 glasses, some say. Drink half your weight in ounces, others say.
Your ancestors would tell you to drink when you’re thirsty. Monitor your urine to ensure it’s clear or light yellow.
Are your ancestors wrong?
