I agree protesting is generally pointless, especially here, but I live in a small city in the north east and thousands of people still showed up. Older on average, and kind of confused on exactly why they were there, but there nonetheless.
It really is just a social event for them.
It's turned into basically "Generic Liberal Protest"--Trump represents everything they hate--not supporting Ukraine, not supporting Palestinians, cutting leftist govt jobs and big govt handouts, anti-trans/gay policies, etc. So it's a melange of weirdos with blue hair, Boomers singing 60s protest songs, Pride flags, whites wearing keffiyehs, DOGE haters, race batters, Forever COVID maskers, Open Borders types, etc all wrapped up in hating Trump as an almost abstract Emmanuel Goldstien.
A lot of unfocused sound and fury signifying nothing but numbers they can use, in certain cities, to proclaim a lot of support.
It cannot be overstated how minimal the progress in actual advanced aging is. Every "life extension" thing you've ever seen is a scam. We are no better at meaningfully treating the diseases of senescence than we were decades ago. Huge amounts of research money have been flushed down the drain going down blind alleys for dementia treatments and cures, but none worked, and now the fact remains that by age 100, nearly all people are progressing rapidly into senility
Yeah, no matter what it just seems to be genetic luck of the draw. Some people can go to 90s and 100s and seem spry, but then one year they just hit a wall and lose it fast, as opposed to others who decline slowly or early. You can do some things with lifestyle to mitigate it--two siblings might have very different death ages depending on diet, exercise, alcohol, etc. But there doesn't seem to be much you can do to prevent dying at 75 or 85 or 105.
Look at famous people in their 90s like Dick Van Dyke, Clint Eastwood, William Shatner. They look good now, Eastwood is gonna direct another movie. This is Shatner walking around in NYC a week ago at 94:

And see how he acts here, how lively:
If you said he was 70, it would be believable. And he might be just as good in 6 months, or a year. But 10 years from now, probably 5, maybe 2, he'll hit a wall that a 70 year old in the same shape might not hit at 80.
I remember seeing there was an old black dude that was like 110 or something who still drive his old pickup truck and smoke and drank. Then a year or two later he dropped dead. Nobody has ever beat Jeanne Calment. 30 years ago people thought she was the wave of the future, but it seems more like she was just a genetic freak in a good way, like Manute Bol.
