At 25 you might think about marriage, so that is the time when a person starts understanding love and relationships.
At 28 you will start getting passionate about things around you.
At 32 your analytical skills start developing. Mid level managerial skills usually shine at this point.

Placement of planets
Each of these planets are placed on the charts different for each person. The effect of each planet will also be different depending on several factors. For eg placement of Venus can bring in a partner for a long term relation like marriage. Or it can help you to discover more about yourself before settling down for any long term commitment.
Placement of planets in various houses will also indicate what type of reward is expected. This also differs with age too since the requirement of people at different ages is not the same.
