Good tool design is important in the prevention of overuse injuries. Well-designed tools and equipment will require less force to operate them and prevent awkward(别扭的)hand positions. They will allow the worker to keep the elbows(肘)next to the body to prevent damage to the shoulder and arm.
Overuse injuries can therefore be prevented or reduced if the employer provides, and workers use:
●power tools rather than having to use muscle power
●tools with specially designed handles that allow the wrist to keep straight (See figure 1). This means that hands and wrists are kept in the same position as they would be if they were hanging relaxed at a person’s side
Figure1. Bend the tool, not the wrist
●tools with handles that can be held comfortably by the whole hand. This means having a selection of sizes-remember that tools that provide a comfortable firm hold for a person with a very large hand may be of no use for someone with a very small hand. This is a particularly important consideration for women who may use tools originally designed for men.
●tools that do not press fingers (or flesh) between the handles, and whose handles do not have sharp edges or a small surface area.

If you’re interested in staying healthy as you age — and living longer — you might want to add a different set of muscles to your workout routine; your creative ones.
Think—and travel—outside the box
“People who travel tend to be more creative,” said Darya Zabelina, a psychology professor at the University of Arkansas. Traveling encourages people to reexamine their models of reality. Some studies show that travelers have more creative success, and that people who enjoy unfamiliar experiences perform better on open-ended questions calling for many ideas.
Generating ideas is one part of the creativity, but knowledge is required to identify the ones that will work. Even if mental speed declines, a person’s base of knowledge is well-preserved as it expands over time.
“You have more to draw on,” said Nye, who thinks her creativity improved when she reached her 60s.

Four Ways to Improve Your Mental Health
Mental health is your overall psychological well-being. And while taking care of your mental health can mean seeking professional support and treatment, it also means adopting some new methods to improve your emotional health.
Tell yourself something positive. How you think about yourself can have a powerful effect on how you feel. When we think about our life negatively, we can end up viewing experiences that way.
Focus on one thing at the moment. Being mindful of the present moment allows us to let go of negative emotions from past experiences that weigh us down. Start by bringing awareness to routine activities, such as taking a shower, eating lunch, or walking home. Paying attention to the sounds, smells, or tastes of these experiences helps you focus.
Exercise. Exercise is a powerful antidote (良方) to stress or anxiety. Look for small ways to add activities to your day, like taking the stairs instead of the lift. To get the most benefit, aim for at least 30 minutes a day outdoors.
A.Open up to someone. |
B.Do something for someone else. |
C.Exposure to sunlight helps your body produce vitamin D. |
D.Making changes will pay off in all aspects of your life. |
E.Instead, practice using words that promote feelings of self-worth. |
F.When your mind wanders, just bring it back to what you are doing. |
G.Don’t wait until you’re in a crisis to make your mental health a priority. |
