Many people with cancer like to get mail because it shows that someone is going out of their way to support them. Sending a card does not put the person with cancer under any pressure to respond in person, but gets the simple message of 'Thinking of you' across to them. Keep in mind that you probably don't know the person's exact situation so it might be better to error on the side of neutrality.
Best Answer: According to a scientist at the Forest Reserve District in Illinois, The life span of an average adult housefly is from 20-30 days, and may even survive freezing weather if it stays indoors.
It is most commonly found in areas where humans live, specifically where there are large amounts of farm animals as well. The lifecycle of a fly, which includes metamorphosis from egg and larval stages to adult, takes about 7 to 10 days in warm summer weather. In colder weather periods, it may take up to 2 months for this process to complete. In ideal conditions, there may be up to 12 generations that occur for flies in just one year and even more in regions with tropical climates.
