up-vote for the fair question. I was under the impression that information was common knowledge among SV elites. The person who initially told me was close to paypal people. How this came about it went something like this:

me - Hey I noticed earlier photos of Musk and he looks so different.

the other person - oh yeah, this whole surgery thing was known among some paypal people I know....

Ignoring the above conversation. His facial changes are sort of going against the pattern of aging.

1 - his receding hairline (starting 10 years ago) is reversing and it's almost gone now. http://img838.imageshack.us/img838/201/elonbeforeafter.jpg

2 - usually people go from high cheekbone to rounded face as they age not usually the reverse. http://www.stepbrother.co.za/images/musk2.jpg

also the scar just under his left eye is not there anymore http://www.inc.com/uploaded_files/image/feature-80-Musk-1-pa...

That said, I'm rather embarrassed for posting this and reply to your comment. But I find it intriguing what you need to do as a visionary since image is everything and there is probably something we can all learn from this.
