What do fingernails tell about a person?

The natural shape of the fingernails can be an indication of susceptibility to certain diseases. Very often a person is not aware of the diseases that his/her parents suffered from, however it takes a few seconds to define a genetic disposition for a certain disease only by looking at fingernails.
It is considered that:
- People with very long fingernails indicate a propensity for pulmonary diseases, and the probability even increases if fingernails are curved and grooved.
- The fingernails that are very curved, but short, indicate a propensity to quinsy, asthma and bronchitis.
- Long, bluish fingernails, which have broad upper part tell about bad blood circulation, that was caused by health weakening or by nervous exhaustion. (Very often women at the age ranges 14-21, 42-47 have this indications)
- Big lunulas indicate good blood circulation.
- Short and small fingernails which are thinner and flatter in the lower part of the fingernail(very often with small lunulas or even without them) exemplify a weak heart.
- Short and very flat fingernails indicate nervous disorder.
- Very smooth fingernails, which are curved on the sides are a clue for propensity for paralysis (especially if the nails are white and fragile)
- A large amount of spots on the fingernails indicate unhealthy nervous system.
- Thin and small fingernails indicate weak health and a lack of energy.
- Very narrow, long, curved fingernails indicate propensity for spine diseases. Physically strong people don’t have this kind of fingernails.
