Interesting - but there are 3 identical ones in the middle row going down….so not sure how you can tell whether it is a hypertension headache, caffeine headache or exertion headache?!

I was just wondering the same thing. Was thinking about how too much caffeine can result in over exertion, which can then raises BP. Either way, bad headache!
