This. My dad had cataracts and was afraid of walking at night because he was worried about tripping. He finally had them done 2 years ago and he said it was night and day (no pun). He also had his vision adjusted, so he has to wear reading glasses instead of just taking off his glasses to read.
Eye related, but this applies to me. I had my eyes checked 1.5 years ago and got a prescription for bi-focals. Whatever adjustment they gave me for reading is already too weak. I'm taking my glasses off again to read. Back to the optometrist I go.
So update on my dad. When I went back to see him, I brought several types of food enzymes and told him he to take them to see what happens. My mom made sure he was taking them according to the instructions. Lo and behold, his GI tract has improved a lot. No more diarrhea and he's no longer afraid of shitting his pants when he's out. He's gained a few pounds back, which is awesome. Him and my mom are coming to stay with us for the summer, so I'll try to fatten him up a bit. ***
*** On that note, he was hit by a motorcycle a few years ago. The bike spun him around and his head hit the pavement. They did emergency surgery to drain the blood but he lost most of his sense of smell during the recovery. He can only taste sweet and salty, which sucks because he used to savor food. He still likes the texture of a good steak though, so I'll ask my boy to keep making grandpa some kick ass steaks while they're staying with us.
