>>40665040 (OP)But there are a lot of things as important as mem-
ory. There's your reaction time. Most people react
too slowly in emergencies. Let's say it takes you half
a second to pull your hand off a hot stove. That's
many times too long a period to have your hand on
that stove.
Or let’s say you require a third of a second to see
the car ahead stop and to start to put on your own
brakes. That's too long. A lot of accidents happen, be-
cause of slow reaction time.
In the case of an athlete, reaction time is a direct
index as to how capable he may be in a sport. So it
assists one in many ways to be able to react quickly.
Self Analysis speeds up reaction time. Here's a
trick. Take a dollar bill, unfolded. Have somebody
hold it vertically above your hand. Open your thumb
and index finger just below the lower edge of the
bill. Now let your friend let go. You try to close
thumb and index finger on the bill. Did you miss it,
snapping after it had gone all the way through? That’s
very slow reaction. Did you catch it by its upper edge
when it was almost gone? That’s much too slow. Did
you catch it on Washington’s face? That’s fair. Or
did you catch it on the lower edge, even before it real-
ly got started? That’s the way it should be. Less ac-
cidents, greater general alertness. Well, barring ac-
tual physical damage to hand or arm, Self Analysis
will speed that up for you.
