Doctors say you can do some simple math to help measure your overall health.
It's all in the numbers, and we're not talking about height and weight.
Doctors say you should be looking at blood pressure levels. The average person should have pressure less than 130 over 80. They should also monitor their blood glucose levels and their cholesterol.
Total cholesterol should be under 100, and triglycerides should be under 150, experts say. LDL, often referred to as bad cholesterol, also should be kept within a health range.
Another category to watch is body mass index, which can be calculated using height and wight. A normal BMI is anywhere from 18 to 25.
Common chemical may lower IQs
A chemical in a lot of household products may be hurting children's IQ's, according to a CNN report.
Women who had a high amount of the chemicals called di-n-butyl phthalate and di-isobutyl phthalate in their bodies during pregnancy gave birth to children who had markedly lower IQ scores, according to a study running in the journal PLOS One.
Phthalates make plastics more flexible and harder to break. These plasticizers are also good at helping chemicals carry a particular scent.
The study found that by the age of 7, children exposed to more of these chemicals had IQ's that were more than six points lower than children exposed to lower levels of the chemicals.
Scientists still haven't pinpointed the exact reason for why that chemical affects people the way it does. They're already planning more studies.
