Winter can take some of the blame, but the cold isn't really the cause of the illnesses around us. The real culprit for catching viruses is a lack of ventilation.

It's true that it's important to keep the body warm so that it remains healthy and stimulates blood circulation, but don't exaggerate. Any doctor will confirm that there's no need to overheat rooms. On the contrary, ventilating the spaces can reduce the chance of infection.

The Pentagon can identify targets from afar using a laser to measure heartbeats Technology is being developed for U.S. Special Operations for surveillance Infrared lasers are able to penetrate clothing and skin to monitor blood flow Heartbeats are completely unique unlike faces or even thumbprints Prototypes currently have a range of about 200 meters or 219 yards As noted by MIT, companies like Nymi are already using cardiac signatures -- taken via a wrist-mounted pulse sensor -- to identify people for security purposes.

Background Cognitive difficulties and autonomic dysfunction have been reported separately in patients with chronic fatigue syndrome (CFS). A role for heart rate variability (HRV) in cognitive flexibility has been demonstrated in healthy individuals, but this relationship has not as yet been examined in CFS. The objective of this study was to examine the relationship between HRV and cognitive performance in patients with CFS. Results Patients with CFS showed no deficits in performance accuracy, but were significantly slower than healthy controls. CFS was further characterized by low and unresponsive HRV; greater heart rate (HR) reactivity and prolonged HR-recovery after cognitive challenge....
