Feet: Size, Cheese Smell and other Curiosities

a distance of about 4 - 5 times around the world.

Considering that the circumference of the Earth is 40,075 km, we are talking about distances in the order of 160,300 - 200,375 km.

If we then take a high-level runner, this can also cover 5,000 km per year of running.

using microorganisms taken from the human body, at the level of the hands, feet, nose and armpits.

The microbiological swabs were seeded and replicated in culture media based on fresh pasteurized whole milk, then used for curdling.

From sensory and microbiological analyzes, the two scholars were able to demonstrate profound similarities between the smell of some cheeses and the stench of feet (or armpits), also from a microbiological point of view.

In fact, cheeses and human bacterial flora share similar microbial populations.

, Jeison Orlando Rodriguez Hernandez should wear shoes measuring 62. Just think that a 45 is equivalent to 29 "miserable" cm.

From his 220cm tall, Jeison Orlando also boasts the record as the tallest man in Venezuela.

These record numbers are the result of problems of acromegaly and gigantism, therefore of an "abnormal secretion of growth hormone that accompanies Jeison Orlando since childhood."

, is reversed (that is, if the fingers extend instead of flexing, opening like a fan), we speak of Babinski's sign.

In summary:

• A flexion (downward) of the toes and sole of the foot is recorded in normal conditions (negative Babinski sign);
• An "extension (upward)" of the big toe and a fan-like enlargement of the other toes (Dupré's fan) are recorded in abnormal conditions (positive Babinski's sign).

A positive Babinski sign is not uncommon, even under absolutely normal conditions, up to 2-3 years of life, as the development of the central nervous system is still incomplete at this stage. In the later stages of life, however, a positive Babinski sign is a sign of damage to the corticospinal bundle (which provides for the fine voluntary movements of the muscles and which, in physiological conditions, exerts a tonic inhibition of the reflex).

Babinski's sign can therefore be noted in the case of corticospinal (or pyramidal) lesions, while it is absent in extrapyramidal lesions; it can appear for example in patients with amyotrophic lateral sclerosis and in the terminal stages of diseases such as rabies, hepatic encephalopathy and metachromatic leukodystrophy.

An analogous response to Babinski's sign can be obtained with Oppenheim's sign (swiping the thumb and index finger along the tibial crest from the knee to the foot), with Gordon's sign (compression of the calf with the palm of the hand), with the sign of Chaddock (sliding with a blunt tip under the external malleolus and the lateral edge of the back of the foot, from back to front) and with the sign of Schaefer (forceful compression of the Achilles tendon between the index and thumb) . These "alternative" maneuvers are indicated for those patients who cannot bear the stimulation of the sole of the foot and respond with sudden "discomfort" movements. Furthermore, the negativity of these additional signs significantly diminishes the meaning of a positive Babinski sign.
