I'm fast approaching my use by date, and sadly with aging comes problems like high blood pressure.
Coffee now makes my BP spike, bugger, so think it prudent to limit my consumption to a couple of espresso drinks a day, nope decaf is not an option, to me a bit like washing your feet with your socks on.
Fortunately have recently discovered Hibiscus tea, while not a coffee substitute it really is a very pleasant drink, the down side being, without sugar it really is quite tart, so, limit caffeine intake and increase sugar consumption, cant win. 🙁
