:1) Would I be mad to enrol in EK511?
Hmm... A quick google informs me that EK511 is actually Eric, a 24 year old male from Charlotte, North Carolina, and (presumably) single. Based on that premise, "enrol" sounds like something that should be pronounced in a French accent, and could be energetic, soothing, amusing, or gross (or some combination thereof).
Bottom line: it's up to you, but the airfares could be prohibitive.2) What is time?
An illusion caused by our inability to percieve that everything is happening everywhere simultaneously.3) What is the probability that the answer to this question is equal to 1?
0.5, and Schrödinger wants his cat back. I think. Maybe.4) No really: What is time?
I don't know! I didn't do it!5) Am I crazy to suggest that time was divided into 12 hours for the day because that is readily approximated by the number of hand-spans (at the end of an arm at full extension) that fit into a sky when a person is standing on an open plain? (ie: Hold your arm out toward the horizon. Turn your hand- palm facing you, thumb upward so that the lower edge is in line with the horizon from your perspective. Place the index finger of your opposite hand on top of your thumb to "hold the place" as you move your first hand to sit on top of that index finger. Repeat, working your way up the 'sky'. Report your findings on whether this works for you and whether you think I'm insane.
I think that sounds like an excellent reason, and yes, it did work for me, too.
As for your sanity, I don't think this will alter it much one way or the other.
