Sheesh, and none of you guys are anywhere near the 70's yet!!!! Actually, for me what has been most bothersome is my eyes aging...... Since I really rely on them, having my visual acuity changing over the years has been very disturbing. To me, since I am already hearing-impaired, losing my vision altogether would be a real nightmare.
The hearing impairment thing is something I've had since birth so it's not a big deal to me and actually I find it rather advantageous at times when living in a multifamily (condominium) dwelling, the way that I have been for over 25 years and still am currently doing. Unless the guy who lives above me were to stomp violently on the floor or drop something heavy that makes a loud sound, I am pretty oblivious to a lot of the everyday sounds since I often go around home without bothering to use my hearing aids. His dog barks, no problem (I do hear it when I'm wearing my aids, of course).
I'm much more sensitive to odors and am not appreciative when I smell cigarette smoke from another unit or some weird concoction (what IS that smell? It's not pleasant!) Most mealtime scents are rather aromatic and one wonders, wow, what are they going to be enjoying, as it smells great! One scent I absolutely detest is dryer sheets or other products of that ilk, which usually is sickly-sweet and pollutes the air everywhere when someone does a load or two of laundry and puts their clothing into the dryer with these products...... Why would anyone want their clothes to smell like that???!!!!
Back to the aging thing: when I was in my forties I sustained a herniated lumbar spine disc and had surgery for that, but still have residual reminders from that, which have shown up more and more frequently as I continue to age. Nerve damage which was done at the time of that initial occurrence never was able to fully recover, so there's the occasional twinge and reminder of that horrible sciatic pain or the more-and-more frequent realization of numbness in some of the toes of the left foot. At least right now this doesn't interfere with walking or other activities in any way, thankfully. Occasionally I do have cramping in the night or early morning, which IS uncomfortable, of course, but again is quickly resolved.
No problem here with knees, never have experienced that. Probably because I've never been overweight and also have never participated in the kinds of physical activities which really do take a toll on knees. I do occasionally get pain in my left ankle, which had sustained several serious sprains throughout my life and which my doctor explained now has arthritis. OK, I can deal with that.....
So you guys who are still in your 40's and already experiencing issues with your health and well-being.....there's worse ahead if you're not mindful of taking care of yourself now, and even if you ARE mindful, the aging process is still going to catch up with you anyway as you enter the era of your 50s and the 60s....but most notably, it seems to be the 70s when everything really does seem to happen and remind you of your actual age....
