Introduction to the Kids' COVID Episode
Peter Attia introduces a special COVID series episode in which his daughter Olivia interviews him. He suggests parents may want to bring their kids into this one because it addresses questions kids have been asking.
- •Special COVID series edition for kids
- •Olivia mostly interviews her father
- •Aimed at questions kids and parents may be asking
- •Includes some questions Peter asks Olivia
- 1:49 – 3:59
What Is a Virus and How Small Is It?
Peter explains that a virus is a kind of living thing with genetic material that cannot divide on its own and must infect a host. He uses a cut hair to illustrate how tiny coronaviruses are, and notes that viruses can cause colds and GI bugs.
- •Viruses can't replicate without infecting a host
- •A virus is about 100 nanometers wide
- •About 1,000 coronaviruses could line up across a cut hair tip
- •Many viruses don't harm us, but some cause colds and GI bugs
- 3:59 – 7:39
Where SARS-CoV-2 Came From and Past Coronaviruses
Peter says he's a newcomer who learned from experts, then explains the virus's likely path from bats to pangolins to humans in Wuhan. He compares it with SARS and MERS, which were more lethal but spread less, and says another one could show up.
- •Virus is SARS-CoV-2; disease is COVID-19
- •Likely path: bat to pangolin to human, around November in Wuhan
- •SARS killed about 10% and MERS about 30% of those infected
- •Other coronaviruses cause only miserable colds
- 7:39 – 8:45
When Will Kids Go Back to School?
Olivia asks the question she thinks all kids are wondering. Peter guesses she won't return this school year but says it's too soon to say beyond that because we don't know how many people are infected.
- •Peter guesses no return to school this year
- •Unknown number of infections makes predictions hard
- •Lower-risk people might return sooner if many already had it
- •Quarantine could last longer if more caution is needed
- 8:45 – 13:51
Why the US Has So Many Cases
Peter explains that the US ignored warning signs and lacked pandemic infrastructure like a national stockpile of protective equipment and testing. He compares US deaths to South Korea's and says earlier quarantine would have helped, especially in dense places like New York.
- •Warnings and early sequencing of the virus weren't acted on
- •No national stockpile of protective equipment
- •Testing is key to isolating those who are infected
- •US deaths per million are over five times South Korea's
- •Dense cities like New York amplify spread
- 13:51 – 16:32
Herd Immunity and Risk by Age
Responding to people who want to just get infected and be done, Peter explains herd immunity using chickenpox. He says it's unknown how long immunity lasts and that kids could pass the virus to higher-risk relatives even if they aren't at risk themselves.
- •Herd immunity compared to chickenpox and vaccination
- •Most people, at least 80%, recover
- •Length of immunity is unknown
- •No one Olivia's age has died in the US so far
- •Kids could transmit to grandparents or others at higher risk
- 16:32 – 18:53
Quarantine Practices: Packages and Handwashing
Olivia asks what a proper quarantine looks like, using their routine for Amazon packages. Peter cites a study of how long the virus survives on surfaces and explains why they assume packages may carry virus and wash hands for 20 seconds.
- •Packages are opened outside and contents cleaned
- •Study measured virus survival on cardboard, plastic, steel and copper
- •Virus can live a day or two on cardboard
- •Assume anything arriving might carry virus
- •Wash hands for 20 seconds
- 18:53 – 24:06
Delayed Payoffs, Discipline and Preparedness
Peter uses the question of why the adults failed to prepare as a teaching point about trading present enjoyment for long-term benefit. With Olivia, he discusses ice cream and screen time, 'discipline equals freedom,' and the farming example, saying he hopes this is a wake-up call.
- •Hard to do things when payoff is far off
- •Thought experiment of no parental rules
- •Discipline equals freedom
- •Peter says adults failed to invest in preparedness
- •Farming example shows consequences of skipping work
- 24:06 – 26:32
Is It China's Fault? The Driving Analogy
Olivia asks whether this is China's fault. Peter uses a car-cutting-you-off analogy to argue that while the virus originated in China, the US must take responsibility for how unprepared it was.
- •Easy to blame China
- •Being cut off vs. driving unprepared
- •Both parties share fault when you're not ready
- •The US bungled its response
- •Peter acknowledges the virus originated in China
- 26:32 – 29:12
Olivia on Quarantine, School and Online Classes
Peter flips the interview and asks Olivia about her experience. She describes her shock at leaving school early, missing friends and sports, and struggling with online classes while now appreciating school more.
- •Olivia thought leaving school early was odd
- •Hardest parts: no friends and no sports
- •Online school makes asking questions difficult
- •She and her friends took school for granted
- 29:12 – 34:15
Life at Home: Dad, the Puppy and Zone 2 Workouts
The conversation turns lighter as Olivia talks about her dad being home, the new puppy and her zone 2 workouts. They then wrap up and Peter muses about having her brother Reese on the podcast.
- •Olivia likes her dad being home more
- •The puppy arrived weeks before quarantine
- •Zone 2 workouts at 65-70 watts with lactate around 2.1-2.3
- •Possibility of Reese joining a future episode
