It seems old folks only talk about health issues. I'm not there yet, but it takes up more and more of my conversation. You see ads on TV all the time: sudden urges to go, etc. and advocating medication to shrink your prostate. My nighttimes were showing multiple trips to the bathroom, and on morning bike rides, the number of trees I needed to visit became ridiculous. So, I cut out caffeine. And, I cut out beer and a significant amount of other alcohol (except relapsing on the recent Natchez Trace trip). The result: sleep all night and zero tree stops on my three hour ride last Sunday (and other rides, this started three months ago).
I've found that coffee in the morning is more habit than anything, so three plunges of hazelnut into Starbucks decaf worked, and I only went through three days of headache and didn't have to try to break a 40 year routine. A bonus: coffee in the afternoon, something I previously avoided at all cost.
