Living overseas in Japan, first winter there, caught the worst case of full blown influenza I've ever seen. 104 degree fever for almost two days, time in hospital getting intravenous fluids and tests after test, fever was over 100 for about a week total. Would have been alone, but the family two doors down had a couple kids who I tutored English to, and their mother was kind enough to bring me groceries, juices, soup and shuttle me to the doctor and hospitals as needed. Very kind for someone I had met just a few times previously. Have no clue how she found out I was even sick, either saw me stumbling home the first day I was sick or the small-town nature of the place means news travels fast. Regardless, very thankful. Wound up losing 25+ pounds, but managed to gain it all back within a few months sadly...
