Talk about coffee is always skewed between I have no issues and a single drop after lunch ruins my night.
Caffeines half life in the body is strongly tied to age. As you get older, the half life gets so long you cannot metabolize a normal dose in 24hours. That is why people over a certain age often drink decaf.
So just because you can drink 5 cups a day at 25 doesn't mean it's the same at 65, or even 35.
Are you simply describing the slowing of metabolism for everything consumed, or stating caffeine itself is metabolized slower with age? Curious about a source for the latter.
