Age estimation in adult is a fundamental question in forensic medicine. Although estimation of adult skeletal age at death is one of the most important identifying features in unknown individuals, it is also one of the most difficult to achieve. However in the present global socio-political scenario, an increasing demand also exists for age estimation in living persons, such as immigrants, refugees, asylum. Online Journals are scholarly and peer reviewed journals. The speed at which people age depends on a number of factors including genetic inheritance, lifestyle and mental health. Determining chronological age in both worms and humans is easy – count forward from birth.But determining physiological age has remains subjective – based on how someone looks or functions. Citations are important for a journal to get impact factor. Impact factor is a measure reflecting the average number of citations to recent articles published in the journal. The impact of the journal is influenced by impact factor, the journals with high impact factor are considered more important than those with lower ones. This information can be published in our peer reviewed journal with impact factors and are calculated using citations not only from research articles but also review articles (which tend to receive more citations), editorials, letters, meeting abstracts, short communications, and case reports.
