We are just getting older and older with each New Year. Vigor and wisdom are draining, and bit by bit we are moving away from the amazement of youth. Yet neither fear nor anxiety helps retain youth. Instead, a few living habits help maintain. ●Laugh to your heart's content as much as you can. Laughter helps reduce pressure and improve your immune system, which makes people look 8 years younger. ●Keep an eye on your blood pressure. Those with a blood pressure of 115/75mmHg look 2.5 years younger than those above 160/90mmHg. ●Quit smoking and avoid passive smoking. This can take 8 years off your appearance. ●Spare some time for exercises each day. Exercises need not be tiring. A 20 minute walk every day makes people look 5 years younger. ●Keep learning and absorb something new each day. Speak the same language as the young people. Learning something every day makes people look 2.5 years younger. ●Keep other pressures under control. Too much pressure makes people look 30 years older. If they are good at networking and manage to keep pressure under control, they will look 30 years younger. ●Secure high quality medical care insurance and do whole body check regularly. For those contracted with chronicle diseases, proper treatment and qualification of the diseases makes people look 12 years younger than what they would without proper treatment. 63.
