Are all people on Earth really connected through just six steps?
SEND ME AN EMAIL:
1. Do not send it directly to me unless you know me.
2. Send the email to someone you have met IN PERSON and know on a first name basis AND THEY KNOW YOU.
3. Make the subject line 'Six Degrees of Veritasium'
4. Explain that you're trying to get this email to me and ask them to forward it on to me (only if they know me IRL) or someone they know who might know me.
5. If your email reaches me by Sept. 1, 2015 I will email you back and ask for your address so I can send you a postcard.

Duncan Watts, Six Degrees: The Science of a Connected Age
Albert-Laszlo Barabasi, Linkds: How Everything is Connected to Everything Else
