Like most people who've had a heart attack, I have to take some pills every morning now.
I take Plavix, and I take a children's chewable 81-mg aspirin.
Note that that word "chewable" only refers to one of these:
Please also note the similar size, shape, and color between these two pills.
I submit for your consideration the fact that without my glasses, I am terribly nearsighted (with astigmatism, too).
Thus, I have a lesson to impart. Don't chew the Plavix.
