When Mexico won its independence from Spain in 1821, all the  territories it possessed included Mexico, most of Central America  (Guatemala, El Salvador, Honduras, Nicaraguaâ¦ and Costa Rica) as  well as today's US States of California, Nevada, Utah, Texas,  Arizona, New Mexico, and parts of Colorado and Wyoming.
The average human body temperature is 98.6Âº F or 37Âº C, but it can vary somewhat. Older people average a bit less. These values can also vary with time of day. This means that illness may be present, especially in older adults, even when the temperature appears to be within the normal range.
Normal human body temperature varies slightly from person to person and by the time of day. Consequently, each type of measurement has a range of normal temperatures. The range for normal human body temperatures, taken orally, is 7002309950000000000â 36.8Â±0.5 Â°C (7002309927777777777â 98.2Â±0.9 Â°F).n addition to varying throughout the day, normal body temperature may also differ as much as 0.5 Â°C (0.9 Â°F) from one day to the next, so that the highest or lowest temperatures on one day will not always exactly match the highest or lowest temperatures on the next day.
