This was originally posted to the blog in IsolatedM, the website dedicated to those Mensans who are far-flung, or otherwise separated from a local group. I had occasion to review the site and (re)found this video. The speaker, herself an IsolatedM fellow Mensan, gave this talk at a Ted-x, and I really appreciated what she had to say. Worth a listen.
The direct link to the IsolatedM site is here, (also worth a look.)
