Cognition is a process that is not only about thinking quickly and making risky decisions, but also includes vocabulary skill, critical thinking, data analysis, problem solving, emotion recognition. For example: Vocabulary skill usually peaks at age 60. The language is interesting but not easy to learn. It's not a problem to learn a word, we can learn it for a second or two. However, when we learn 10, 100, 1000 or more words it becomes a really big problem. One of the skills that improve as you get older is critical thinking, which is a very important skill in every aspect. Critical thinking depends on each person, because each of us has different knowledge, background, experience and thinking skills, but this skill can be trained if people focus more on it. Critical thinking usually reaches its peak between the ages of 60 and 70, the same for analysis and problem solving (Jenna Birch, 2015). As people age it is believed that their cognition slowly becomes gradual. Therefore, to make up for their deficiency, they use their critical thinking, problem-solving ability… to come up with a strategy, carefully make a plan, look at different aspects to make decisions that are mostly right and effective. If there is brain decline, I am definitely not capable of doing it
