Try to do some mentalrobics every single day!

One technique for becoming lucid in a dream is to ask yourself if you are dreaming. If you are awake, the answer will clearly be "no". But if you are sleeping, the answer is not so certain. There is a high likelihood that this question will cause you to realize that you are dreaming.

To take advantage of this you should get into the habit of asking yourself on a regular basis if you are dreaming. If it becomes habit, then it is likely that you will ask yourself when you are actually asleep. We have already discussed how you should ask this question whenever you see a dreamsign. Unfortunately, dreams don't always have easily identifiable dreamsigns, so you should try to ask yourself this question at other times of the day. It's difficult to remember to ask yourself this question without any sort of cue, so pick something that you encounter on a regular basis and ask the question whenever you see it. For example, you may ask yourself if you are dreaming every time you walk through a door.

The more you ask yourself this question during the day, the more likely it will be that you do it while asleep.

The human brain reaches its full size by age 20 and then starts shrinking by about 1% per year. Male brains actually shrink slightly faster than female brains, but before you draw any conclusions it should be noted that there is no evidence that brain size determines ability. Rather, it is how your brain is constructed that matters.

The decrease in brain mass is not due to the death of neurons. In fact, recent research is showing that you can actually make new neurons as you age. The shrinkage is mostly due to changes within the neurons. In particular, the number of branching dendrites and connecting synapses decreases with age. Additionally, age causes the deterioration of the protective covering that surrounds the neurons. This may contribute to decreased mental performance.

Smoking, drinking and high cholesterol are all thought to hasten the shrinkage of the brain, so there's yet another reason to give up your vices.

 



Stress has many physiological affects on the human body. As we have already learned, certain types of stress can be good, but too much stress can lead to all sorts of problems.

The first thing that stress does is to cause the adrenal glands to start secreting adrenaline and epinephrine. These hormones are produced to help use get ready to fight or run away from a threat. Fortunately, we don't face mortal danger on daily basis anymore; but unfortunately, this means that these hormones just make use feel a lot of anxiety.

The "flight or fight" reaction also causes our body to have an increased metabolism. Your heart rate increases, your breathing speeds up, you start sweating, and your blood sugar levels increase. If you are temporarily escaping from a lion this is a good thing, but if you are living your life in a constant state of stress, this can lead to some serious problems, such as diabetes and high blood pressure.

Additionally, the body turns off certain unessential functions. After all, if you are running away from a lion there is really no point in wasting energy with things like digestion, reproduction and growth. This is exactly why highly stressed people get ulcers, have trouble getting pregnant and under extreme conditions have stunted growth.

Finding and eliminating stressful parts of our lives is important, but for short term relief, relaxation exercises can be a big help.
