I think this article provides good motivation and a good mental perspective (the big picture) about exercise.

Yes, I have this affliction also. The worst part is not being able to open your eyes. After about thirty seconds of effort I am finally able to open my eyes and maybe raise my head and look around and see that I am not in danger.
There is a hormone that is responsible for sleep paralysis. It...
The deal with cellphones is akin to putting aluminum foil or other metals in the microwave; in both cases, the high-frequency electromagnetic waves cause static electricity to accumulate on the surface of the metals, and then you have arcs and sparks.
For problems like this, which involve an either-or situation which is repeatedly tested, use the binomial distribution.
P(k out of N) =
N!
---------- x (p^k)(q^(N-k))
k!(N-k)!
where:
N = the number of opportunities for event x to occur;
k = the number of times that event x occurs or...
The total number of combinations of nine objects, taken three at a time, is
9 x 8 x 7
-----------
1 x 2 x 3
That is, 84. Since 8 of the combinations are "tic-tac-toe" lines, the probability is 8/84, or about 9.5%
You have to take the logarithm of the observed concentrations before you try to determine the slope. Plotting the logs will give you a reasonably straight line, while plotting the concentrations will give you an exponential curve.
You just have to use the formula for exponential decay throughout this problem.
C = C(0) * exp(-Rt); where C is the momentary concentration and C(0) is the "initial" concentration. R is the rate of decay, which we can figure out from the half-life.
0.5 = 1 * exp(-R * 38m)
ln(0.5) = -R * 38m
* R...
