Lou Gehrig may hot have had what's known as Lou Gehrig's disease.

The baseball player suffered numerous head injuries on the field.

Scientists studying spinal cord levels discovered unique proteins in three athletes who suffered head injuries and developed symptoms of ALS, but other ALS patients didn't have those proteins.

That's sparking speculation in the medical world that Lou Gehrig and other athletes could have had a similar, but different, illness.

Colder days could raise the risk of heart attacks.

Researchers in Great Britain found that a drop in even one degree Celsius on a single day could mean another 200 extra heart attacks.

Older people between the ages of 75 and 84 and those with a history of heart disease seemed to be more vulnerable to temperature changes, while people taking aspirin were less vulnerable.

Why temperature affects the heart is still unclear.

Camel milk does the body good.

The European Commission is considering making camel milk available for consumption.

It's sending a panel to inspect camel dairy farms.

Veterinarians say camel milk is similar in taste and appearance to cow's milk, but it's closer in composition to human milk.

That makes it a healthier option for people, according to the research.
