The decision to monetize DF came after a cancer scare, so it might be reasonable to assume 'enough' would be 'enough to ensure that both of us are comfortably able to handle such a medical emergency'
I'm sure you've heard this already, but it would be far more practical to move to pretty much anywhere other than the US that has free health care. The US is crazy when it comes to this.
Tell Tarn and Zach... but presumably they like living in the US for some reason.
I'm aware of that. I also noted that they mention multiple cancers are not unlikely over time (I'm unable to access the article at this time so I can't quote directly), and they specifically pick the $5M figure as a value that they are uncertain about. I'm suggesting that $5M is probably a reasonable figure to remove any uncertainty.
