Detention near Israeli guard tower

In Hebron a man is detained under an Israeli guard post, sometimes for 15 minutes, sometimes for 3 hours. No one knows how long it will take, and it’s a reminder that your life is not your own; the army exerts absolute control over the day to day life of Palestinians. Makes me wonder, at the end of an average Palestinian’s life, how many days or years have been stolen by the Israeli government?
