| No, people with strong hands tend to live longer.

|
| The article goes on to recommend grip strengthener and I strongly

| the goal.

| Keep care of your hands and wrists. If you feel pain or

|
| _Has_ to just be grip strength correlating with activity level
| and general health, not grip strength _causing_ any of that.

| Well, it doesn't have to be that abstract. Muscles in the

| In fact, the gastrocnemius (calf muscle) has been referred to
| as the "second heart":

| Judo practitioners might be a good population to study for this

| strong grip AND muscle memory of how to fall properly, which
| could be a confounding factor.

|
| Said differently, correlation does not imply causation.

| Rather than being a matter of better access to health care etc,

| are less likely to go out to the golf course. The same applies
| to Vitamin D, taking international flights, and reading books,
| all of which are correlated with reduced death rates.

| Thank you. They always make it sound like X helps you lenghten

| healthy life, not the cause of it.
|
| Strong hands is probably a result of exercise and leading a
| healthy life which leads to higher life expectancy. Meaning
| exercise and leading a healthy life is the cause of strong
| hands and higher life expectancy.
|
| Golf industry says golf lengthens your life. Hand grip industry
| says strong hands lengthen life. Can't help but be a little bit
| cynical the older I get.

|
| Assuming that correlations are spurious is as poor an approach
