Any article citing statistics is invalid when they don't understand the difference between percent and per cent.

FYI: "The one-word percent is standard in American English. Percent is not absent from other varieties of English, but most publications still prefer the two-word per cent. The older forms per-cent, per cent. (per cent followed by a period), and the original per centum have mostly disappeared from the language (although the latter sometimes appears in legal writing).

"There is no difference between percent and per cent. Choosing between them is simply a matter of preference." -- http://grammarist.com/spelling/percent-per-cent/

I guess you don't have any grandparents who live alone, but can no longer reliably identify their own children....You are so deep into denial about the reality of aging

The "reality of aging" does include old people completely destroyed by aging. And we need to get serious about dealing with that, letting people check out when their life ain't no more fun.

But that reality also includes 90-something karate masters who are still practicing.

The "functional limitations" of which the author speaks can, to some degree, be mitigated by lifestyle. So can the supposed "lack of creativity" -- the problem isn't aging, it's stale ideas. Learn something new. Change fields.

My maternal grandfather was still quite aware, oriented, and active in his church at 90. And the heart disease that ultimately did him in could quite likely have been partially prevented or reversed with better lifestyle habits. My paternal grandfather was a bit short of his 79th birthday when complications from coronary bypass surgery (again, largely preventable) did him in. He never really recovered, emotionally, from the loss of his wife (could have used better social support, more community connections), but he was in no way crippled or suffering from dementia in his final years.

So given the example of my grandparents, with good dietary and exercise habits, good social connections, and a little medical help I can hope to get into my 80s with my brains mostly intact. (If we don't completely fsck up the planet, and if we make a few medical breakthroughs, with a little luck I hope to see the dawn of the 22nd century -- I'll only have to reach 131 to do that.)

Of course, I could also get run over by a bus this afternoon, or diagnosed with some particularly nasty cancer next month. One never knows.

If you get a cataract, spend the extra money on a CrystaLens. Unlike 45 year old natural lenses and implants available before 2003, they will actually focus. Of course they're under patent so they're about a thousand dollars each more expensive than other implants. I'm sure I'll have a cataract in the other eye not too long from now, the last eye doctor I saw said "a couple of years" and it's been longer than that.

I think I'll wait until 2023 when the patent runs out and everybody makes them, the ones like my mom has will be obsolete. I only use that eye to look at tiny things, anyway.

Insurance paid for all but the extra thousand, it was the best thousand dollars I ever spent. The device inside my eye is my favorite device of all.

The whole "needles in the eyeball" are just a stepping stone to something truly amazing.

Indeed. I was severely nearsighted all my life, after the cataract surgery I no longer need corrective lenses at all, not even reading glasses and I'm 62. My vision in that eye went from 20/400 to 20/16. Truly a miracle.

BTW, my retina surgeon said that my retinal detachment was a result of being so nearsighted; a nearsighted eyeball isn't perfectly round like a normally sighted person's eyes.

It's a little [illogical] to say a tomato is a vegetable. It's very [illogical] to say it's a suspension bridge.

Logic is a binary function. Something is in a logical set - or it is not. Being illogical is not a synonym for being mistaken. Degrees of precision are irrelevant for set inclusion. Fuzzy logic is not logic.

BTW: It is illogical to conclude that a Tomato in NOT a vegetable, simply because it belongs to a taxonomical subclass, "fruit". It as if I were to say your testicle is not animal.

I'm fine with the chip; that protects me, the bank, and the retailer. I am NOT fine with the PIN. My signature can't be stolen; if someone steals my card, the signature on the sales slip proves it's not me. But if someone steals your PIN they have your every penny.

It happened to me with a debit card. I welcome the chip, but of they add a PIN I'll cancel all my cards and go back to cash and checks, even though they're nowhere as convenient.

I hadn't had any of the accounts I'd used, either, and wasn't sure which one it was. Still got the account back, give 'em a try.

I had cataract surgery on that eye two years before the retina came loose. I did know a couple of guys who had vitrectomies followed by cataract surgery, but the needles don't go through the lens, they go in through the whites (photos at wikipedia). I suspect that a vitrectomy involves steroids; steroid eyedrops for an eye infection caused my cataract.
