From 600+ conversations with the world’s leading thinkers.
The scale of our damage on the animal world is unimaginable. We inflict pain and suffering on wild and domestic animals. We take away their wild lands and habitats, we use them to test our medicines and they're affected by climate change, pollution and many other aspects of our world.
About 65% of the population mouth breathes at night. If you're breathing through your mouth for eight hours, you increase your susceptibility to respiratory illnesses, sleep apnea, snoring, and allergies. You get less oxygen and overwork your body.
A true pet's value lies entirely in its relationship with us, and vice versa. The first fossil evidence of that bond goes back around 30,000 to 40,000 years: dogs buried with humans, including one remarkable case of a dog that had survived two bouts of canine distemper, presumably because its human companion cared for it.
Our senses allow us to perceive, but they're incredibly limited. Science sees far beyond our human blind spots, and the reaches of this 'bubble' our senses create for us. When you're in a bubble, you inhabit a form of fictional reality, and we've seen the dangerous consequences of this in financial bubbles, stock market bubbles, real estate bubbles.
Ultimately, I think we'll be able to pop a pill and reset our body's age. It takes us about 4-8 weeks currently to reset the age of a mouse, it shouldn't be any different for humans.
Cancer, we now know, is a disease caused by the uncontrolled growth of a single cell. This growth is unleashed by mutations- changes in DNA that specifically affect genes that incite unlimited cell growth. In a normal cell, powerful genetic circuits regulate cell division and cell death. In a cancer cell, these circuits have been broken, unleashing a cell that cannot stop growing.
I often joke that disproving quantum computing sceptics is the primary application of a quantum computer, with everything else being a bonus.
But when it comes to claims like 'pets alleviate depression,' there's really no solid evidence. In fact, the findings so far are pretty ambiguous. And in one study that found no significant overall effect, cat owners were actually more depressed than the control group.
The heart is a fascinating machine. It beats 3 billion times in a typical human lifetime, consumes so much energy, and does so much work that if you attached a heart to a typical swimming pool – the heart would empty the pool in about a week.
I remember being on a spacewalk and had a few seconds to see a view that humans were not meant to see. It was like I was hearing from God. But then, I had to get back to work.
What we see in the science is something very different. We often see that romantic partners basically see the best in each other. They're wearing rose-coloured glasses. And the primary thing that brings people together is what we would call attachment bonds or pair bonds: the idea that people are looking for somebody who they feel has their back, somebody who's going to celebrate their successes, and somebody who's going to be there for them.
When considering the prevalence of this disease, we're speaking of 7 million diagnosed patients in the US. But how many Americans currently have the initial stages of Alzheimer's already festering in their brains? I concur with the higher estimates, suggesting around 40 million people.
