Harvard Women’s Health Watch says moderate coffee consumption can improve cognitive function and improve endurance performance. It’s rich in antioxidants, too. I like antioxidants, I like cognition and endurance. I also like coffee. I try not to drink it, though. I try really, really hard. I limit myself to a cup a week and won’t even make it at home, but go out and buy it, hence paying more. It has not been the disincentive I’d hoped.
