No. Your boy is a mutant. Congrats!
The Black Death occurred from 1347-1353. It killed more than 1/3 of Europe's population alone, carried by fleas on rats.
It probably came from merchants that arrived from China.
The sea ports were hit first-- Sicily, near Italy. Like the Renaissance, from Italy it soon spread throughout Europe. Unlike the Renaissance, it brought with it poverty, confusion, and chaos.
Remember Monty Python's "Bring out yer dead!"? That is believed to be a joke that arose from cartdrivers who would go around collecting corpses during the Bubonic Plague (Black Death).
Hope that helps.
it is a lymph node probably
well that depends... do you wear anything like a necklace that moves around in your pectoral area.. if so this could mean you are allergic to that type of metal (yes this happens) or maybe something else irritates that area, but for it to go away and come back it must be that, try keeping your shirt off and other things and just lie around for the day if it just appear and goes with nothing touching that area i suggest you see a doctor
Rosacea is the first thing that comes to mind. Although, if you have been coughing or vomiting, they could very well just been broken blood vessels which should disappear within a few days.
