Can our age change hardware performance?

It will be interesting to see the Gillette study. I have not heard that before about gray hair. As for the ubiquitous common knowledge, it is often only common.

Clever.

No, accurate.

Not the reference i was thinking of but another:

"If your beard hair is white, greying or red, curly, or coarse, allow more time for preliminary soaking to soften it. If it is dark, straight and fine, time spent preparing the beard can be shortened. This was confirmed in a four-year study made by Drs. Lester Hollander and El-bridge J. Casselman at the Mellon Institute, Pittsburgh., They showed that a sample of dark hair stretched (by softening) to 0.58% of its full length after soaking 20 seconds in water at 86°F. White hair in the same time stretched to only 0.10% of its full length."

Thank you for that link. An interesting article, although I do not think it was worth the price. This article is very well researched and presented, and uses the article you cited as one of its references:

Insights into shaving and its impact on skin
Wiley Online Library
https://www.google.com/url?sa=t&source=w...11.10783.x

It makes no mention of age as a factor in shaving.

This article states that gray hair is less coarse than pigmented hair:

"Hair strands become smaller and have less pigment. So the thick, coarse hair of a young adult eventually becomes thin, fine, light-colored hair."

Perhaps new information gas been discovered since the 1930s?

As i suggested white/grey hair is oftentimes described as coarse because it feels brittle from the lack of oils which assist in softening. It this requires more prep time even though it is not actually more coarse or thicker.

I have read the Wiley article, that changes in hair structure with age wasn't looked at means only it wasn't looked at. Neither does the other linked article contradict this description.

In my case, it's the changes in skin, over time, that I focus on.

Skin thins with age, and is much less elastic. I find that my best shaves result from warmed skin, well-cleaned and moisturized before shaving.

I use alum frequently during pass 2 (ATG) to pull the skin gently taut as I move along. Skipping across a wrinkle instead, almost guarantees me a weepah.

This makes a big difference in both the quality and closeness of the shave. It also means less backtracking, which reduces skin irritation, especially if I'm determined to go after a few strays. Knowing when to call it a shave is important too, in my opinion.

I expect to be using sharper blades, and milder razors going forward as well.

Older folks are also sometimes on certain medications, like techy blood thinners which can make skin more delicate, and more easily damaged as a side effect...

I'm 72 and yes, I've noticed a difference as I get older.
Thinner skin for sure, plus 'wrinkles'...where did they come from?
Only old people get wrinkles surely?
It's winter here and maybe that alters the skin too. Might need some face cream to soften and plump up the skin?
My timeless .68 was just fine last year, now I need to get the .95 to get the same close shave.
Blades are the same, soaps are the same (I only have 4 different soaps).
My Tech is no good now. Put away to live in a drawer.
In my case, because my skin seems 'harder' now (thinner but harder if that makes sense), I find that I can't get a close shave such as I was getting last year.
Well it's certainly a good reason/excuse to buy another razor though isn't it?
