Stress affects older adults more than young adults

A new study examines how stress affects decision-making in older and younger adults, revealing that stressed older adults alter their behavior more significantly. The researchers found that stressed older adults were not only more cautious but also jerkier drivers, braking almost three times as much as their calmer peers.

Cholesterol-lowering drugs may also lower PSA, but whether they cut cancer risk is still not known

Popular cholesterol-busting drugs statins appear to lower men's PSA values along with their cholesterol levels. However, it remains unclear whether statins prevent prostate cancer growth or just mask it. The study found that PSA levels declined by an average of about four percent after starting statins.
