They settled around the Mediterranean and Black sea, which helped spread culture.
According to Philip R.Shaver, there are three "behavioral systems" that play a role in romantic love: attachment, caregiving and sexual attraction.
You view love as an attachment when you are emotionally dependent on the other person for your happiness, safety and security, while love as caregiving refers to the great pleasure you receive from supporting, caring for and taking of a loved one.
Lastly, love as a sexual attraction is when you can't get the other person out of your mind and the thought of him or her excites you and turns you on.
If we will based the statement above from Shaver's model, we can say that the love being felt by John and Cynthia for each other transcends from attachment love to caregiving love.
Technology has always been closely linked to the ways in which people have lived. Before the development of civilization, humans lived for many millennia with tools and techniques that allowed them to live successfully in a wide variety of environments. From primitive stone implements to fairly sophisticated and specialized tools, prehistoric humans developed technologies that allowed them to increase their control over the natural world. In return, the tools that they used increasingly changed their way of life.
