I always hold my chin with my fingers, cover my mouth or lace my fingers in front of my mouth. And I tend to look upwards. Got one? Or a place in which you think very well?

[Tendency]

I cross my legs almost always. The garden is usually the best place or anywhere that a fresh batch of air can soothe.

[xGravity]

I lie on my back, put my hands under my head and my eyes scan what's above.

My bed is the best spot.

[Elovan]

I don't really have a pose, but if I'm thinking or concentrating really hard I'll stick my tongue out a little bit. Makes it kind of awkward when I don't realize it and someone asks why I'm sticking my tongue out. xD

[sunrisespirit]

I'll look up and around
My friends always ask what I'm staring at, but I'm just thinking :D

[Kito]

I turn into my avatar except I look up instead of down.

[Skinnyman]

I usually lean my head on my hand (doesnt matter which one :P) and make a thinking face or i just go and walk my dog and watch the moon xD

[StrawberryDreams]

I've just caught myself with two fingers prodding into my face staring into thin air, so perhaps that's it. xD Otherwise, I have several, although unfortunately, I usually just look gormless when I'm deep in thought. If you're flexible enough, the lotus position I've found to be quite good for deep thinking, since it somehow seems to 'free' your upper body from your lower.

[TheMadSwede]

I raise my eyebrows and make my eyes bug out.

I like to think in the basement of the library. More like a crypt.

[SocioApathetic]

My ISFP friend tilts her head to the side and stares right past me. It's creepy, to say the least.
