One never stops learning new things. In the last three years a new industry developed in Israel, with about fifty quant trading companies. Almost all learned the profession in Zahal's Unit 8200 which must be the largest math incubator of the world.
In the pic Nir Glikstein, 39 y.o., who lives next to Kever Benjamin City, is the founder of the most succesful of the quant partnerships (2008 profits 230 million dollars, 2009 - 170 million). When I drive to Petach Tikva, I see his name on the sign at his modest moshav house. They have 150 traders working from a Herzliya office, trading in the Seoul stock exchange and who knows where else. The whole thing is so anonymous that few know of their existence, or who are the capitalist partners and how works their FINAL algorithm.
At least they have a good answer to the eternal question:
"Dad, if you are so smart, why aren't we rich?"
"Son, we are, we are."
