After watching the video Secret Life of the Brain: Aging Brain, it is surprising to see some of statistics in the film and to realize that happiness is lowest at the age around 30 to 50. However, it makes sense to me because people at the age of 30 to 50 will need to find ways not only to take care their kids but also their parents. It puts many people in a difficult situation. After they use their money for their kids’ tuition and their parents' health care insurance, they hardly have any time to save up money for themselves before they retire. My neighbor is also in the same situation. After she helps her daughter pays for her college tuition, my neighbor has to quit her jobs because her father becomes too sick to live on his own, so my neighbor needs to takes care of him. It is tough for her because she hardly has her own time. She rarely has spare time to do something that she loves. It is sad to see that many people are being trapped in this scenario. In addition, data also indicates the level of happiness will eventually go up after retirement.
