Thank you sir, that response made my day.

For context, drownproofing was a course once upon a time at Georgia Tech which is now more famously taught in the Navy SEALS. It teaches you not so much how to swim but how to bob just below the surface without drowning or expending too much energy. The "final exam" was having your ankles and wrists bound and being dropped in the pool.

There's a startup metaphor in there somewhere.

Is this really Charles Isbell or someone pretending to be him? Account created within the last hour.

I look forward to it.
