Cough and drop your pants...
To improve your reaction time ,try dropping a ruler and catching it
The speed of your reflexes and after a few goes, your ability to learn.
Have one person hold a ruler at one end dangling down. Have the test subject place their fingers around but not touching the very bottom of the ruler. Without warning the first person releases the ruler to fall. Visually the test subject sees the falling ruler and attempts to grab it as soon as they see it drop. Measure the distance of travel on the ruler. Some simple calculations (gravity, acceleration, etc.) will give you the reactio time. Multiple test attempts will increase accuracy.
It doesn't measure the exact reaction time. Just the average.
