I thoughtlessly forgot that my aunt wore dentures (probably for 30 years) and could not eat the corn for lunch, at least not off the cob. My wife, who is capable of eating 8 ears of this corn in one sitting, was more than willing to relieve my aunt of her serving.
Dentures can be a real limitation, and now that there are dental implants I hope that more and more people will learn about them and realize what a good investment they are. But if you can't afford them, at least get dentures that fit really well.
Eating is one of the pleasures of life, and there's no reason not to enjoy it your entire life. Taking care of your teeth to avoid losing them is obviously the best approach. That means finding a dentist that you love and will see regularly.
My aunt, she grabbed the corn back from my wife and sliced it off the cob and ate it. She's old, but she's not crazy!
