2. **Historical Context:**
- The term was coined by Elie Metchnikoff in 1903, marking the formal recognition of this field of study.

3. **Scope of Gerontology:**
- Gerontology encompasses various aspects of aging, including:
- **Biological Aspects:** The physiological changes that occur as organisms age.
- **Psychological Aspects:** The mental changes and challenges faced by aging individuals.
- **Cultural Aspects:** How different cultures perceive and treat the elderly.
- **Social Aspects:** The impact of aging on social structures and relationships.
- **Cognitive Aspects:** Changes in cognitive functions such as memory and reasoning with age.

4. **Conclusion:**
- Therefore, Gerontology is the branch of science that deals with the study of aging and the various factors associated with it, making it distinct from other fields such as ornithology (study of birds), osteology (study of bones), or geology (study of the earth).

**Final Answer:**
Gerontology is the branch of science that deals with the study of aging and the various aspects associated with it.
