A simple truth. Maturing is a never-ending process. People think being an adult is the peak of being mature, and yet, we never stop maturing and changing. However, people sure do try to resist the aging process.
Modern consumer culture is youth-obsessed, and as a result, people tend to look down upon becoming an elder. People get upset when seeing they have a grey hair or feel they are losing their youthful lifestyles. The fear of aging goes against a person.
Fighting maturity is a trap since then you are fighting yourself.
