Senior citizens tend to have the most need for health care, and the demand on Medicare is increasing. The 35 million elderly folks will increase to 71 million by 2030. That is 20% of the US population.
However, each year the rich US government officials try to slash Medicare benefits to patients and payment to health care providers. Right now you pay more at the gas pump to fill your car than Medicare pays your doctor for a 15 minute visit. Hmmm, maybe I should start selling gas at the office? My nurses can fill your tank while I treat your congestive heart failure.
I didn’t realize George W. Bush is only 62. I thought he was 108. (Isn’t it interesting how presidency makes men old? Bill Clinton went from a hip saxophone player to Father Time during his presidency.) But on July 15, 2008, almost-Medicare-eligible Bush vetoed the legislation to stop a 10.6% cut in payments to doctors. Hello! I don’t see him cutting fuel prices (or his own salary).

Food Poisoning occurs about 76 million times a year in Americans, leading to over 300,000 hospitalizations and 5,000 deaths. Ones most hurt by food poisoning are the elderly, immunocompromised, and young kids. Food poisoning is usually from bacteria, but also viruses and chemical ingestion. Incubation time most c/w: <1 hr chemical ingestion, 1-7 hrs toxins from staph aureus or bacillus cereus, 8-14 hours bacteria, and 15 or more hrs viruses.
For outbreaks, Salmonella is #1. Though Listeria account for like 0.2% cases, it is the #1 cause of death from food poison outbreaks. #2 is viruses, in particular norovirus. Chemical ingestion and then parasites follow.
