Protecting Sight #273: We have no idea where camels really come from. White cataract double rhexis & optic tract syndrome. Mental models & the power of compounding.

Welcome to my daily learning journal. My daily goal is to watch one Ted Talk and one cataract surgery. I also plan to read one journal article and read/listen to a book chapter, podcast, or significant work.

Here is today’s list:

1. Ted Talk – Latif Nasser: You have no idea where camels really come from. “Camels are so well adapted to the desert that it’s hard to imagine them living anywhere else. But what if we have them pegged all wrong? What if those big humps, feet and eyes were evolved for a different climate and a different time? In this talk, join Radiolab’s Latif Nasser as he tells the surprising story of how a very tiny, very strange fossil upended the way he sees camels, and the world. This talk comes from the PBS special “TED Talks: Science & Wonder.”” (

This is a fun & insightful Ted talk!

2. Cataract Surgery – Uday Devgan MD – 1040: White Cataract Double Rhexis.

Excellent technique.

3. Andrew Lee MD – Optic Tract Syndrome.

Dr. Lee’s neuro-ophthalmology reviews are around 5 minutes and filled with high-yield pearls.


I enjoyed this episode and forwarded to my nieces and nephews. Excellent discussion on mental models and the power of compounding.

5. Tax-efficient fund placement (Bogleheads) – This is the most important tax-efficient portfolio allocation graphic I’ve ever come across. As stated on the Bogleheads wiki, “This article describes how to minimize taxes through appropriate placement of investments in tax-deferred or taxable (pay taxes now) accounts.”

I share this page often with friends and family.
