Studies show that the average middle-aged woman displays about 3.5 millimetres of the maxillary incisors when the lips are at rest. However, dentists recommend that the denture should be set to expose a maximum of 2 millimetres at rest, which is even undesired in aesthetically driven patients who prefer between 3 and 4 millimetres exposure. A beautiful smile requires that the ends of the maxillary incisors almost touch the lower lip, but leave a maximum distance of 3 millimetres. Aesthetic recontouring and conservative restorative dentistry can be used to treat any slight digressions from the tooth patterns described. Restorative dentistry, however, is not advised in incidences with perfect tooth shape and tincture as it only produces mutilations to the healthy tooth structure. Such incidences can be remedied by orthodontics.

The above-mentioned parameters are useful in the designing of a smile. When appropriately followed, these aspects help maintain the aesthetic zone of smile and enable a clinician produce results that are pleasing to the patient.
Apart from the shape, colour and position of the teeth, healthy and harmonious gingival is also important for an aesthetic youthful smile. The recent advancements in restoration procedures have made dentists even more aware of this fact. The position of the smile line is influential in governing the periodontal visibility. There is little information concerning the relationship between the visibility of the periodontium and teeth during smiling (Liebart et al., 2004). A previous study in 1980 by Crispin and Watson as cited by Liebart et al. reports that the gingival margin can be seen in 66% of 425 subjects during natural smiling (2004). Conversely, the gingival margin is seen in 84% of the participants during a forced smile. However, Crispin and Watson do not provide information for patients without an interproximal papilla even when the said loss is the key issue of concern. Liebart et al. observe that some studies report similar observations, but other studies only focus on the natural smile leaving out the forced smile (a study by Jensen et al. in 1999) while another study by Tjian et al. in 1984 does not specify the type of smile (2004). The following figures show the differences in the appearance of the smile line in the natural and forced smile.
Five hundred and seventy-six (576) subjects between the age of 21 and 78 take part in the study. Out of these, 364 are females while 212 are males. All the participants have equal distribution of the anterior and posterior teeth between both sides of their jaws. All the subjects have healthy periodontium though a number of them have a healthy but reduced periodontium. Different pictures are taken of the natural and forced smile for each participant. A panel of seven examiners then examines the photos to determine the position of the smile.
It is realized that 89.06 % of the study population expose their periodontium in natural and forced smile further showing that a pleasant smile involves the exposure of healthy gingival. The disturbance of the gingival contour due to depression, changed passive flare-up, or poor arrangement of teeth leads to an unattractive smile. In addition, it is realized that there is a substantial difference in the fraction of subjects who display their periodontium during the forced smile (90%) compared to 60% in the natural smile. These findings lay emphasis on the importance of examining the forced (maximal) smile during the evaluation of gingival visibility (Liebart et al., 2004).
An aesthetically pleasant smile is a function of a healthy gingival, a comparative amount of gingival display during smiling as well as synchronization in the dimension, outline, arrangement and colour of the teeth (Ashtaputre & Rathi, 2012). The disproportionate exposure of the gingival leads to what can be expressed as a gummy smile, which is the chief source of awkwardness among patients. In such a smile, the gingival is the predominant feature that overshadows the lips and the teeth. A normal smile may lead to the exposure of the gingival to some extent in approximately half of the patients. However, an inflated smile reveals the gingival in three quarters of patients. A normal smile exposes the gingival between the lower boundary of the upper lip and the gingival margin of the mid incisors by between 1 and 2 millimetres (Ashtaputre & Rathi, 2012). In contrast, a gummy smile reveals up to 4 millimetres of the gingival.

The intertidal zone is an extreme ecosystem because it constantly experiences drastic changes. It is located on marine coastlines, including rocky shores and sandy beaches. The intertidal zone experiences two different states: one at low tide when it is exposed to the air and the other at high tide when it is submerged in seawater. The zone is completely submerged by the tide once or twice every day. This ecosystem is rife with research opportunities for marine researchers like National Geographic grantee Swapnale Gole, who studies the behavior of sea anemones, crustaceans, and fish in the intertidal zones of the Andaman Islands in India.
At rocky shorelines, tide pools can form in holes, cracks, or crevices where seawater collects as the tide goes out. Organisms that cannot normally survive low tide conditions, like sea stars, shrimp, or fish, can take refuge in these pools. Sandy shores provide sediments in which organisms bury themselves to stay cool and moist during low tide. Where a species lives within the intertidal zone depends on its tolerance of underwater and above-water conditions. The presence of predators and species that compete for the same space and food also impact where an organism will be found.
The intertidal zone can be further divided into three zones: high tide, middle tide, and low tide. The high tide zone is only submerged at high tide and is hotter and drier as a result. The middle tide zone is submerged and exposed for equal amounts of time. The low tide zone is only exposed during low tide and has the greatest biodiversity of the three zones because it provides more favorable conditions for those organisms that cannot tolerate air exposure for long.
While conditions in the intertidal zone can be extreme, it is home to many living things and is also an important feeding spot for both resident and migrating birds. This ecosystem also provides protection against erosion and keeps storm waves from reaching buildings along the shore.

People stay in their comfort zone to avoid feelings of anxiety or stress, and pain. Anything outside the comfort zone creates uncertainty, and uncertainty makes us feel anxious. Naturally, human beings are wired to avoid these feelings. This makes them reluctant to leave their comfort zone.
Increased performance is just one of the many reasons stepping out of your comfort zone is important. It also helps you find out your true potential, reach your goals, and live a more fulfilling life.
Studies show that regular exercise decreases the effects of stress on the body, lowering anxiety levels. This makes it easier for you to try things outside your comfort zone, as one of the barriers to stepping outside of it is the feeling of anxiety that it triggers.
The comfort zone is a mental state that does not allow personal growth. It may be okay to be there for a while, but if you want to continue to grow and adjust to new situations, this is not a place to stay.
You can be uncomfortable without being scared. Being uncomfortable is a normal and healthy part of life that can't be avoided. When faced with something new or different, most people experience some degree of discomfort at first but they usually adapt to the situation after getting used to it.
