Carson Jenner Norma Barksdale Writing 201 February 28, 2024 The Amazing Writing Approach of Edward Hoagland Edward Hoagland’s “On Aging” is one of the best essays that I have read.

Chromosomes are pulled apart during mitosis; this not a gentle process. To prevent this important genetic information from being lost from the ends of the chromosome, telomeres protect this important information from being lost by taking the loss of its own base pairs. During mitosis, when the telomeres lose some base pairs, they can remain shortened and lead to further breakdown of the telomere, or the enzyme telomerase can add new base pairs allowing new generations of daughter cells to follow. A wild-type (WT) yeast mother cell will stop going through mitosis when it has created about 25 daughter cells. When the telomerase is inactivated, shortening occurs in the late after telomerase inactivation (LTI) which has similarities to normal

Secured attachment is extremely important in the developmental stages of an infant. Secure attachment is when an infant feels distressed when they are separated from their caregivers and feels happy when their caregiver returns. Research from this article suggests that, when an infant does not receive the comfort they need from their caregiver for secure attachments, it can have a negative impact on their behaviour later on in their childhood and throughout life. Infants who have secured attachments tend to develop stronger self-esteem as they grow older, they also tend to be more independent and successful in socialising. Those children are also less likely to experience less depression and anxiety.

The term “ageism” was created by Robert Neil Butler in 1969 because he recognized the discrimination against elderly people. Butler, who was an author, physician, psychiatrist, and gerontologist, was known as the founder of the International Longevity Center (ILC) and National Institute on Aging (NIA).
