Input: Consider Input: Context: When is a person considered an adult? That depends. Most teens become physically mature by the age of 16 or so. But they are not adults in a legal sense until they are older. For example, in the U.S., you must be 18 to vote. Once adulthood begins, it can be divided into three stages: (1) early, (2) middle, and (3) late adulthood. Early adulthood starts at age 18 or 21. It continues until the mid-30s. During early adulthood, people are at their physical peak. They are also usually in good health. The ability to have children is greatest during early adulthood, as well. This is the stage of life when most people complete their education. They are likely to begin a career or take a full-time job. Many people also marry and start a family during early adulthood. Middle adulthood begins in the mid-30s. It continues until the mid-60s. During middle adulthood, people start to show signs of aging. Their hair slowly turns gray. Their skin develops wrinkles. The risk of health problems also increases during middle adulthood. For example, heart disease, cancer, and diabetes become more common during this time. This is the stage of life when people are most likely to achieve career goals. Their children also grow up and may leave home during this stage. Late adulthood begins in the mid-60s. It continues until death. This is the stage of life when most people retire from work. They are also likely to reflect on their life. They may focus on their grandchildren. During late adulthood, people are not as physically able. For example, they usually have less muscle and slower reflexes. Their immune system also doesnt work as well as it used to. As a result, they have a harder time fighting diseases like the flu. The risk of developing diseases such as heart disease and cancer continues to rise. Arthritis is also common. In arthritis, joints wear out and become stiff and painful. As many as one in four late adults may develop Alzheimers disease. In this disease, brain changes cause mental abilities to decrease. This family picture shows females in each of the three stages of life. Which stage does each represent? Despite problems such as these, many people remain healthy and active into their 80s or even 90s. Do you want to be one of them? Then adopt a healthy lifestyle now and follow it for life. Doing so will increase your chances of staying healthy and active to an old age. Exercising the body and brain help prevent the physical and mental effects of aging. 
 Question: during this time, brain changes cause mental abilities to decrease.

Output: late adulthood

Input: Consider Input: Context: McLeod syndrome is a rare X-linked hematologic and neuromuscular disorder manifested by chorea, myopathy, cardiomyopathy, areflexia, hyperCKemia, and acanthocytosis. Only four mutations have been reported in the gene responsible for McLeod syndrome. We report a novel gene mutation in a Japanese family. Direct sequencing of the PCR-amplified genomic DNA revealed the mutation was a single C-nucleotide insertion at codon 151 in exon 2 of the XK gene, which resulted in a 3'-frameshift. Study of family members revealed that the patient's mother was a manifesting carrier heterozygous for this mutation. 
 Question: Mutation of which gene is associated with McLeod syndrome?


Output: xk
