Reasonable suspicion does not apply if a person simply refuses to answer questions or is of a certain ethnicity or race. If a person is suspected of committing a violent crime, such as robbery or murder, the police officer may frisk the suspect's clothing to check for weapons.
Middle age technically refers to reaching an age where you have lived half the average life expectancy for your gender. The average midpoint of life is now about 40 for women and 38 for men (men tend to die 6 to 8 years before women). In comparison, 100 years ago women arrived at middle age by 22, mainly because so many died in childbirth.
This is the monthly menstrual bleeding (also called menstrual period) that women have from their early teen years until menopause, around age 50. The menstrual cycle is from Day 1 of bleeding to Day 1 of the next time of bleeding. Although the average cycle is 28 days, it is normal to have a cycle that is shorter or longer. Girls usually start having menstrual periods between the ages of 11 and 14. Women usually start to have fewer periods between ages 39 and 51. Women in their 40s and teens may have cycles that are longer or change a lot. If you are a teen, your cycles should even out with time.
