sun, addiction, sugar the starter drug

Bright sunny day again, a few clouds reduced the high to 70. I counted 5 hammocks and quite a few campers, tents, RVs, etc. Strange as it is still January. Everybody is in a good mood.

I know a tall blonde lady jogger who carries a pistol and is going on a police raid today near the county seat / court. Meth house. Her job is to rescue the children and take them to foster homes while the courts try to figure out what to do with them. Very stressful and dangerous. Anything can happen and always sad. She is looking to change jobs, and runs along the lake all the time to relieve stress.

Probably the main problem around here is sugar. Sugar lights up brain pleasure centers similar to drugs. Alcohol is slightly processed sugar. Children get lots of soda pop and sweets, then they go on to get addicted to worse drugs. Refined sugar and grains are not natural foods. Before modern times people maybe could find some fruits or berries or honey if some bear did not eat it before they got to it. Nowadays people are just getting fat, addicted, and modern diseases by sweets. Unfortunately junk food is subsidized by the government. Junk food is often more expensive than plain natural foods. And the diseases boost the economy – very expensive to treat.

https://en.wikipedia.org/wiki/Nucleus_accumbens

the nucleus accumbens has a significant role in the cognitive processing of aversion, motivation, pleasure, reward and reinforcement learning;

hence, it has a significant role in addiction.

It plays a lesser role in processing fear (a form of aversion), impulsivity, and the placebo effect

These neurons are activated directly or indirectly by euphoriant drugs (e.g., amphetamine, opiates, etc.) and by participating in rewarding experiences (e.g., sex, music, exercise, etc.

the cognitive processing of motivational salience (wanting) as well as reward perception and positive reinforcement effects. Particularly important are the effects of drug and naturally rewarding stimuli on the NAc shell because these effects are related to addiction. Addictive drugs have a larger effect on dopamine release in the shell than in the core

Dopamine is related to recreational drugs including amphetamines, cocaine, and morphine, which increase extracellular levels of dopamine in both the NAc shell and the NAc core, but the effect of these increases is more pronounced in the shell.

The nucleus accumbens, being one part of the reward system, plays an important role in processing rewarding stimuli, reinforcing stimuli (e.g., food and water), and those which are both rewarding and reinforcing (addictive drugs, sex, and exercise).

The nucleus accumbens is selectively activated during the perception of pleasant, emotionally arousing pictures and during mental imagery of pleasant, emotional scenes.

A 2005 study found that it is involved in the regulation of emotions induced by music, perhaps consequent to its role in mediating dopamine release. The nucleus accumbens plays a role in rhythmic timing and is considered to be of central importance to the limbic-motor interface (Mogensen).

In rats, stimulation of the ventral tegmental area causes the release of dopamine in the nucleus accumbens much in the same way as addictive drugs and natural reinforcers, such as water or food, initiate the release of dopamine in the nucleus accumbens.

The same results have been seen in human subjects in functional imaging studies. For example, increased dopamine concentration is seen in the extracellular fluid of the nucleus accumbens when subjects believed they were being given money

increased activation (i.e., increased fMRI BOLD signal-change) was observed among heterosexual males viewing pictures of attractive women.
