<p>[QUOTE=&quot;Ocatarinetabellatchitchix, post: 7963966, member: 99554&quot;]I gained 50 pounds during the pandemic; I&#039;m now weighting 180 lbs. Not too bad you may think. But since I&#039;m only 4&#039;10, my BMI is now 37.6... What does that mean ?</p><p>The link between body weight and health has been generally acknowledged. Many studies have shown that being overweight and underweight can both lead to health problems. A person’s healthy weight is determined using the body mass index (BMI) and waist circumference. BMI is a simple correlation between weight and height. Once calculated, it can help to assess the risk of developing various diseases over time. The BMI is defined as the body mass divided by the square of the body height, and is expressed in units of kg/m², resulting from mass in kilograms and height in metres. Here are the meaning of your results:</p><p><br /></p><p>Underweight = &lt;18.5</p><p><br /></p><p>Normal weight = 18.5–24.9 </p><p><br /></p><p>Overweight = 25–29.9 </p><p><br /></p><p>Obesity = BMI of 30 or greater </p><p><br /></p><p>So 180 lbs is not necessarily fat, but compare to my height I&#039;m chubby obese.</p><p><br /></p><p>[ATTACH=full]1380773[/ATTACH] </p><p>Fernando Botero sculpture in Yerevan Armenia</p><p><br /></p><p>I also own coins that are overweight, meaning heavier compared to other specimens of the same issue or type. In antiquity, how did the master of the workshop ensure that each coins produced was of equal weight? It all started with the blanks before stamping. Experimental archeology seems to indicate that the only way to obtain calibrated weights is to melt a number of very small balls, the weight of which has itself been checked beforehand. These very small balls can be made by throwing molten metal into cold water through a screen. </p><p><br /></p><p>[ATTACH=full]1380771[/ATTACH] </p><p>G.F. Hill, 1922 p.6</p><p><br /></p><p>In the case of excessive weight, we can still lighten the flan before the strike, as we see on many republican coins reworked with the gouge. In practice, the control was not the same depending on the metal. To use medieval terminology, if the gold coins and probably silver were weighed <i>al pezzo</i>, meaning by the piece, the bronze coins were in turn weighed <i>al marco</i>, meaning together according to a number determined for a measure of weight (eg. Roman pounds). There was obviously a tolerance measure accepted for each of the emissions. </p><p><br /></p><p>In summary, the master of the workshop had to work according to a theoretical weight on the one hand, an emission tolerance on the other. He had to produce a determined number of coins from a unit of weight while ensuring, in the case of gold and silver, that the weight of each copy was not below a certain threshold.</p><p><br /></p><p>But in some cases, often cause by the political situation, the weight of certain issue had a wide tolerance compare to the average standard. I&#039;ll show three obvious example in my collection, two of them from the Gallic Empire and the last one from Philip the Arab. </p><p><br /></p><p>[ATTACH=full]1380772[/ATTACH] </p><p><br /></p><p>Victorinus VICTORIA AVG&nbsp; <b>5.25g</b></p><p><br /></p><p>The average weight of 41 specimens in the Mairat PhD is <b>3.07g</b>, with the world record (?) at 5.65g for this type.
