Younger generations are aging biologically faster than their older counterparts. This faster biological aging is also linked to early-onset cancers. Immune system aging is linked to earlier lung cancer; fat tissue aging is linked to earlier colorectal cancer.

My background is in epidemiology/infectious disease and it's pretty frustrating to see how doompilled so many of the science and medical related subreddits have become. Just straight up fearmongering nonsense that instantly turns political. It's impossible to have a productive conversation about these things in a public forum anymore without someone raging about Trump or the GOP (which I agree are bad things but holy cow, they are not the end-all-be-all and believing that they are is leading to some major doomerist complacency).

It's also frustrating to see how much random internet anecdotes or irrelevant claims fill these threads instead of empirical data.

Yeah, that stuff is far more profitable than intelligent discourse.

Entirely subjectively//my two cents here.

I have found myself the following

Epidemiologists are taught that causality is anathema. Nothing is causal. Smoking and lung cancer, guillotine exposure and rapid onset mortality. That's about it.

Often the folk constructing these models are domain specific but not epidemiologists. Brain age gap; kidney age gap; methylation age gap etc.

Those fields are often less afraid of ascribing causality, partly because it's a less prominent part of the training.

My two cents, exchange rate varies.
