Chewing gum while cutting onions can reduce eye irritation because it increases the frequency of swallowing, which helps clear the tear ducts and prevents the onion's sulfur compounds from lingering and triggering tears. The gum keeps your jaw moving and promotes more swallowing, though the effect isn't 100% foolproof.

Human bone tissue is remarkably strong - pound for pound, it has a compressive strength comparable to granite. Bone can withstand tremendous pressure and weight relative to its size. This makes it an ideal structural material for the body, providing both strength and some flexibility to prevent shattering upon impact.

The stapes bone, located in the middle ear, is indeed the only bone that is fully developed at birth. All other bones in the human body continue to grow and develop after birth, reaching full size at different ages.

These are widely accepted textbook values for human anatomy. An adult human has approximately 206 bones, around 600 skeletal muscles, 22 internal organs, and an estimated 100 trillion cells (though cell count varies by individual).

The correct answer is True. Research has shown that the ratio of ring finger length to index finger length (2D:4D ratio) correlates with prenatal testosterone exposure. A longer ring finger indicates higher testosterone levels in utero, which has been linked to various health outcomes including lower risk of heart disease. This is based on epidemiological studies showing correlations between finger length ratios and certain health conditions.

Alan Turing designed the Automatic Computing Engine (ACE). It was one of the first designs for a stored-program computer. PDP11 and Honeywell are much later computer systems/manufacturers.
