1. Telomerase is an enzyme that rebuilds telomeres at the tips of chromosomes. 2. If telomeres become too short, cells can no longer divide, which can lead to the development of tumours and a range of diseases. 3. Ultimately, telomerase cannot keep up telomere production at a sufficient pace, and over time cells lose their ability to divide, causing aging and, in the end, cell death. 4. Lymphocytes are cells that produce antibodies that fight infection. 5. Chronic life stressors and brief life stressors both wear down the immune system and increase the likelihood of illness.
