Another single basic mechanism (for some in the world, anyway) is: acceptance.

Not saying you have to like death. But it's all around us, and people who live closer to nature get to see death regularly, from carnivorous animals (little choice) to plants which green, bear fruit, and fade away in fall. Most people don't ever need to embrace death, but recognize it's part of the natural order.

Denial points us away from the real and is mentally unhealthy. Acceptance releases us from that potential fear and stress. It also encourages us to truly appreciate what we have, especially while we have it, and ever afterward for our good fortune while we had it. Life is change.

Acceptance reminds us to 'drink life to the lees', like Omar Khayyam. Not to waste our time on adverts, or fashion trends, or fretting about things we can't do anything about, or worrying about what might be. When we're sure we've done our best in this wiggy world, we need ask ourselves no more. Compassion for ourselves empowers us to share that with others.

Elephants know this as well. As do many pack animals.

The first two claims are not really supportable:

Human beings are the only living things that are truly aware of their own mortality and spend time pondering the meaning of life and death.[24] Awareness of human mortality arose some 150,000 years ago.[25]

The claim that only humans are aware of mortality is from an article about COVID and death anxiety by 3 psychologists, no primatologists, paleontologist or animal behavior specialist. Recently published elephant burials and long documented chimp and corvid mourning behavior could undermine this claim. Although an emotional reaction to death may not imply awareness of one's own death.

The second claim that mortality awareness is only 150,000 years old is sourced to a 25 year old psychology paper. Our understanding of the human past has radically transformed since then. Sima de los Huesos may show mortuary practice from 400,000+ years ago, Dinaledi chamber may show non-sapiens mortuary practice from 200,000+. And if erectus (2M - 100k y/a) had fire, boats and language or proto-language well mortality awareness doesn't seem out of the question.

There's no good reason to think we know when awareness of death arose.

I think animals have a better grasp on death than we do.

I bought my first dog at 5 years old. He came with neuropathy in his hind legs that slowly progressed. I'd have to counterbalance him when he pooed so he wouldn't sink down into it. He had to wear shoes so he wouldn't wear his nails down to bleeding stumps. He was prescribed meds, but they only helped him with any pain.

One November it snowed early, and on our walk he went down twice. The second time I almost wasn't able to get him up. I returned home, sobbing, and I told him that I didn't know what to do. That if he stopped eating, I'd know it was time. (He was always a big eater.)

I brought him his breakfast, and he just looked at me like, "we had a deal," and refused to eat.

I had to pick him up out of the car, and we petted him until he passed. I still feel guilty as if I should have been able to do more. But I'll never forget the look in his eyes. He knew it was time, and he accepted it. His only concern was trying to help me be okay.

Intelligence might be largely a human thing. But we have a lot to learn about wisdom.

bullshit.

scientists are sure elefants know about their own mortality.

why is english wikipedia so dumb?

I don’t know if you still want help or if this will work, but I’m always calmed by the inevitability of death. It’s the one thing that’s definitely supposed to happen.
