A person's identity changes ....... while aging
on some occasions

When he joined the army and later as a Tv journalist
he became less sensitive
he became more sensitive
he remained the same person

His involvement with politics turned him into a
callous person
conscious person
sociable person

The national environment of a country can change a foreigner's identity
to a certain extent
depending on the person's sensitivity

He is thankful that he has worked for Unicef because he
earned quite a lot of money
had a better insight of countries in pain
became a war reporter
