Childhood disability rates continue to rise.
Researchers took a look at data between 2001 and 2011.
They found that while there was a decline in the number of physical disabilities, mental health and developmental disabilities rose 16 percent.. particularly among more well-off families.

And a new study shows high-intensity exercise is safe and effective in long-term heart transplant recipients.
Researchers compared high-intensity training to the currently recommended moderate-training in 16 stable patients living with a new heart for more than a year.
They found high-intensity interval training for a few minutes at close to the maximum heart rate...actually helped patients reach higher levels of exercise capacity... and gain better control of their blood pressure.
