[F]ree speech is the wrong framework to be thinking about this, and... it has very little to do with college campuses. ...What happened at Evergreen … - Bret Weinstein

[T]here is something very significant in this question of the hubris involved in imagining that you're going to improve the discussion by censoring... [T]he majority of concepts at the fringe are nonsense... but the heterodoxy at the fringe, which is indistinguishable at the beginning from the nonsense ideas, is the key to progress. So if you decide... the fringe is 99% garbage, let's just get rid of it. ...Yeah, but that 1% ... is the key. ...Eric makes an excellent point about the distinction between ideas and personal attacks, ... [T]here's no value in allowing people to destroy each other's lives, even if there's a technical legal defense for it. Now, how you draw that line, I don't know... Yes, people should be free to traffic in bad ideas, and they should be free to expose that the ideas are bad, and hopefully that process results in better ideas winning out.

Antagonistic pleiotropy, the evolutionary theory of senescence, posits that age related somatic decline is the inevitable late-life by-product of adaptations that increase fitness in early life. That... provides the foundation for an integrative theory of vertebrate that reconciles aspects of the 'accumulated damage' 'metabolic rate', and 'oxidative stress' models.

[C]aptive-rodent breeding protocols, designed to increase reproductive output, simultaneously exert strong selection against reproductive senescence and virtually eliminate selection that would otherwise favor tumor suppression. This appears to have greatly elongated the telomeres of laboratory mice. With their telomeric failsafe effectively disabled, these animals are unreliable models of normal senescence and tumor formation. Safety tests employing these animals likely overestimate cancer risks and underestimate tissue damage and consequent accelerated senescence.
