"Who let the dogs out?"

I came across this interesting blog post by Juan Carlos Lopez, the editor of Nature Medicine. 

Check out the front and back cover of the latest Nature issue, in a PDF format. 

If you don't see it as soon as you open it, zoom out to 50% and flip the page 90 degrees counter-clockwise. Do you see it? Sorry, y'all, those who do not have access to Acrobat Professional, and therefore, cannot flip pages. But despair not, I have just the solution for you - Do as I did:

1)  Stand facing the computer monitor, lining up with an imaginary line 3 inches from its right side.

2) Raise your left leg sideways till it's parallel to the floor. 

3) Bend sideways at the waist (to the right) till your "held-straight" upper body is parallel to the floor. This pose should fit you like a "T". hahaha

4) Try to keep your eyes open through the pain of cramping muscles.

Now do you see it?
