📋 Summary

Insights from 'Something You Should Know'

This episode of Something You Should Know explores a variety of practical and existential topics, ranging from the mundane details of signing legal documents to the profound human need for social connection and our enduring fascination with extraterrestrial life.

The Truth About Ink Colors on Legal Documents

Many people believe that legal documents must be signed in blue or black ink to be valid. Mike Carruthers clarifies that while there is no federal law mandating a specific color, using blue or black ink remains a "smart choice." The primary reason is practical: blue ink contrasts sharply with black printed text, allowing document handlers to easily verify that a signature is an original rather than a photocopy. Conversely, red or light-colored inks should be avoided as they can cause issues with scanners, potentially slowing down processing or raising flags. Ultimately, the legal validity hinges on the intent to sign and agreement to the terms, rather than the specific hue of the ink.

Our Enduring Obsession with Aliens

Science writer Becky Ferrara, author of First Contact: The Story of Our Obsession with Aliens, discusses why humans are so preoccupied with the existence of extraterrestrial life. Ferrara argues that this fascination is not a modern phenomenon driven by pop culture, but rather a deep-seated human trait dating back tens of thousands of years. Early humans "personified the sky" to survive, turning constellations into characters and weaving tales about the heavens.

Ferrara notes that while many people are "alien optimists" due to the sheer statistical probability of life elsewhere in a vast universe, there is a clear distinction between the scientific search for life and the fringe belief that aliens have visited Earth. She rejects the "Ancient Aliens" theory, stating that human achievements, such as ancient monuments, are a "testament to our own species" rather than evidence of extraterrestrial intervention. Regarding government conspiracies like Area 51, Ferrara suggests that while governments have historically engaged in minor cover-ups to protect experimental spy craft or Cold War programs, the idea of a large-scale, decades-long cover-up of alien contact is unlikely, as such a secret would be nearly impossible to contain.

The Loneliness Epidemic and Social Infrastructure

Ken Stern, author of Healthy to 100, addresses the rising crisis of loneliness. He emphasizes that social connection is not merely a lifestyle preference but a "core ingredient for long, healthy living." Stern explains that technology—specifically television and phones—has significantly interfered with our ability to maintain deep social bonds.

Unlike the U.S., countries like Japan and South Korea have integrated "social health infrastructure" into their aging strategies. This includes promoting lifelong learning, intergenerational relationships, and encouraging seniors to remain active in the workforce, not necessarily for financial reasons, but to foster "physical proximity" to others. Stern stresses that friendship requires time—often 50 hours for a new acquaintance and 200 hours for a close friend—and suggests that volunteering is an effective way to meet people because it places individuals in consistent proximity to others who share similar values.

Debunking the Myth of Crossing Your Legs

Finally, the episode addresses the common health warning that crossing your legs leads to varicose veins or circulation issues. Vascular surgeon Dr. John Modrall confirms this is a myth. While a 2007 study observed a temporary, minor rise in blood pressure when crossing legs, it posed no long-term cardiovascular risk. Factors like genetics, age, and pregnancy are the true culprits behind varicose veins, not posture. The bottom line is that the body naturally shifts when uncomfortable, making it safe to cross your legs as you please.

Then, are we alone in the universe?
Are there aliens out there?
It's a question humans are obsessed with.
There's no culture that doesn't do it.
So I really do think that that indicates that we have always had this premonition that we're not alone in the universe, and that we kind of enact that by looking to the stars and telling interesting stories about what might be there.
