I turn 79 this week and feel like I am in pretty decent health for my age. I did have quintuple bypass surgery 26 years ago, and did have a kidney removed for renal cancer 7 years ago, but for the most part I am still active and alert. But lately I added a small metal pill container to my keyring with a few regular aspirins inside. I know that if I suffered a heart attack, chewing an aspirin could make a real difference in my chances of survival. My wife thinks I'm being a bit paranoid, but said as long as it is on my keyring and I'm not asking her to add another item to her already heavy keyring she doesn't really care. Am I being just cautious, or is this a sign of old age paranoia?
