I thought we were supposed to provide facts from our own mental databases... I know a lot of information but not a lot of trivial facts. I'll see what I can do. These might not be 100% exact to the detail, but I'm doing them from memory.
Aspirin is derived from a tree that had been used medicinally for a very very long time.
Aspirin is also chemically related to the popular acne-fighting and hyperkeratosis treatment ingredient salicylic acid, a beta hydroxy acid which exfoliates by melting the surface of the skin and the inside of the pores (unique property, it can permeate oil, alpha hydroxy's can't). It's the only beta hydroxy acid, while there are multiple alpha hydroxy acids.
Hair and skin have a natural pH range of 4.5 - 5.5
Hairs on the head (tertiary) grow an average of 1/2" a month. Eyebrows (Secondary) grow i believe 1/8 - 1/16" a month.
Over all of your normal skin (excluding nipples, perhaps some other places), sebaceous (oil) glands are only located inside hair follicles, and hte oil only secretes onto the surface of the skin through the follicle opening. Real "pores" are technically only sweat pores, which do not get "clogged".
Using scrubs (with hard little scrubbing abrasive beads in them) in the long run will make your skin thicker and rougher, as the beads cause micro tears in the epidermis, causing the skin to thicken the epidermis in defense. A thickened epidermis means more visible wrinkles, possibly more problems with acne and folliculitis, and roughness.
Grass can communicate warning signals chemically to other areas of grass when it is being cut, eaten by insects, etc. The other areas of grass prepare natural defenses, which tend to repel the offending insects.
Your fingertips and lips correspond to the largest of the areas in the brain devoted to senses (which run in strips down either side of your brain and are sectioned by area).
The Phantom Limb phenomenon, where an amputee still senses and feels the amputated limb... Let's use the hand (or arm perhaps?) for example. Once the hand is amputated and the nerves are gone the nerves from the face, which correspond to the section on the surface of the brain next to the hands, "take over" the vacant space in the hand sensation center in the brain. Thus, as you feel you have a face, you also feel you have the hand. In a little research done, an ice cube was moved on the face of a man with an amputated arm, and he felt the coldness sensation in his phantom arm.
Also, the status of the phantom limb will depend on your body image and what your brain expects of the limb... in cases where the limb was paralyzed for a significant period of time before amputation, the limb is also immobile. This can be relieved through illusionary visual feedback producing the illusion of the phantom limb using a mirror image of the other limb. The person is told to try to move the phantom limb in mirror-image movements of the movement of their other limb, and from the visual feedback of the phantom limb moving as they command it to, it regains mobility.
As obvious from this, a large part of the phantom limb is from body image, what your brain is trained (or innately) to expect of your body. In a woman who was born with no arms, her whole life she had phantom arms which were mobile. I believ it was this particular case where the patient could "stretch" her phantom limbs to all different lengths... but I am not positive on that one.
On another note pertaining to this.... the foot and the genitals are next to eachother on these sensory centers of the brain. So if you're going to get something amputated, get your foot amputated. It has been reported that orgasms are twice as intense, since they are also simultaneously experienced in the phantom foot.
