You can dial-up a clearer mind when you set the thermostat at home. A
 study found that you think best when the room is at an air temperature 
that makes you feel the most comfortable. Researchers believe that 
working in a comfortable temperature slows the use of energy required to
 do mental tasks. Source Link
Is
 the “five-second rule” safe to live by? It depends on where the food 
lands. Researchers found that a cookie or sticky food dropped on 
carpeting was unlikely to pick up much bacteria in just five seconds. 
But dropping the same food on a hard floor or outdoors had a higher risk
 of bacterial transfer. Source Link
A
 job that requires more brain work now could help keep you sharp long 
after retirement. A long-term study found that challenging jobs could 
enhance and protect mental functioning in later life. This included jobs
 with data analysis, developing objectives and strategies, making 
decisions, solving problems, evaluating information and thinking 
creatively. Source Link
