Stan has traveled 29.3 kilometers from his home in Toronto to the home of his friend in a Mississauga high-rise. Befor he gets out of his car, Stan puts on a surgical mask, leather gloves, and sunglasses. Stan wears the mask because he is worried about sever Acute Respiratory Syndrome, a disease which has a global case fatality rate of between seven and fifteen percent-- estimates vary. He is also worried about Ebola haemorrhagic fever, which has a global fatality rate of about 90%. Two nearly-recovered patients with SARS are presently 47.2 km away from Stan in Toronto General Hospital. the nearest Ebola patients are in Africa, 12,580 km from Stan. Stan is not wooried about Mrs. Emelda Foster, who is cleaning a penthouse apartment. IF Stan even knew about Mrs. Foster, he would appreciate his enthusiasm for bleach as a disinfectant. Mrs. Foster's eyesight is not what it is used to be, nad she compensates by going ove the same surface repeatedly. Stan wears gloves because he is worried about spider bites. the only venomous spider in Ontario is the northern widow, which produces venom fifteen times as toxic as the venom of a prairie rattlesnake. Although the spider injects much less venom than the snake with each bite, nearly 1% of l. various bites are fatal. Fatalities are concentrated in the very young and the very sick. Stan is 37 years old and in good physical condition. still, he does not put his hand where he cannot see, and he wears gloves just in case. Stan is not worried about Tanya Scott, the 4 year-old girl who lives in the penthouse apartment where Mrs. Emelda Foster is cleaning. If Stan knew of little Tanya's existence, he would appreciate Mrs. Fosters diligence with the vacuum cleaner everywhere in the apartment, even on the balcony. There are zero spider webs in the penthouse apartment. Stan wears sunglasses. The sun is expected to radiate peacefully for another 5 billion years, but in the course of that time its luminosity will double to a brilliance that Stan finds alarming. Stan does not worry about a glass swan figurine weighing 457g. Yesterday Tanya Scott moved the swan from its place on the coffe table from the balcony railing where she could see it in the sunlight. Tanya left the swan on the railing. Mrs. Foster does not see the swan when she brings the vacuum cleaner out to the tidy up balcony. She knocks the swan from railing with the vacuum cleaner wand. At the moment that the swan begins its descent, Stan is 38m from a point directly below the falling swan. He is proceeding to that point in a straight line at a steady pace of 3.2km per hour. Afalling object accelerates at the rate of approximately 10m/second/second. The railing is 112m above the sidewalk. QUESTION: Is Stan worrying about the right things?;-)
