- Stays at home for a long time
- Asymmetrical tree shape
- Rare, long, prickly needles
- Cones round

Use of smell
Use of smell – If a particular scent can trigger specific emotions can therefore affect our behavior and decisions, eg. Buying (from 70s known that emotions decide the election to a much greater extent than quality or price). Properly applied smell can be a powerful tool for manipulation, is likely to attract other people (customers, employees or partners) desirable behavior.
Electronic nose – Detects and analyzes smells
Electronic nose – E-nose is a device that detects and analyzes smells. It successfully replaces the human organ of smell, eg. When assessing the quality of the product.
Mole stereo smell
Mole stereo smell – During experiments with moles. Neuroscientists from the University of Vanderbildt in the US observed the repetitive patterns of behavior. The proof of the existence of stereo-smell of moles was an experiment in which scientists put the nostrils of moles plastic tubes, each facing in the opposite direction. Moles were so lost, that went on back and forth, and in most cases they can not find food.
Fear like perfume
Fear like perfume – Researchers from the University of Munich showed that fear is spreading through the air. Just to our brain she sensed fear pheromones contained in sweat stressed people and they begin to be afraid. Feeling fear pushes us to hasty and risky behavior.

Monosodium glutamate – Enhances taste and smell

Pure monosodium glutamate has no taste, and added to food enhances its taste and smell. For this reason, it is a component of bouillon cubes, Chinese soups, Vegeta, and other spices.
Animal olfactory opportunities
Animal olfactory opportunities – Researchers at the University of Tokyo compared the number of genes responsible for the sense of smell in 13 mammals, including man. It turned out that of all the animals tested was the elephant has the most olfactory genes – in 1948. In second place came the rat (1207 genes), followed by the cow (1186 genes). Dogs of 811 genes were in the middle of the statement, and a man of 396 genes was ninth. Worst fell orangutan, which has only 296 olfactory genes.
Memory likes colors – Using your favorite colors
Memory likes colors – It is assumed that 83% of the information received by sight, hearing 11%, 3.5% smell, touch 1.5% and 1% flavor. Remembering and the huge impact of color is because using your favorite colors while taking notes. Makes we gain emotional relation to the content and thus better remember.
