Input: Consider Input: (CNN) -- Each year, more than 3 million Muslims commit to Hajj, the pilgrimage to Mecca that represents the fifth and final "pillar" of Islam and the largest annual human gathering on the planet. Every Muslim who is physically and financially able to do so is expected to make this pilgrimage once in their lifetime. As described in the Hadith of Gabriel, each pillar of Islam acts as a guide to day-to-day conduct for Muslims, outlining proper professions to God, prayer and spiritual mindfulness, not unlike the Book of Common Prayer for Anglicans or Judaism's Siddur. For this year's Hajj, iReporters from around the world documented their journeys, describing their experiences as they complete this Islamic sacrament. Thanks to the power of social media and platforms like CNN's iReport, they've been able to share their faith with the world, giving Muslims and non-Muslims alike a glimpse of the significance of this powerful and transformative event.More young Muslims embarking on Islamic pilgrimage than ever before2011 Hajj could be a flashpoint for global Islamic revivalPilgrimage is a defining moment in the life of MuslimsFollow iReporters as they complete their Hajj

Input: Consider Input: The Romans may have marched across Britain and left many impressive monuments, but few of their footprints remain.

Although it has not been confirmed that the teenager was a soldier, men were able to join the military between the ages of 16 to 50.Roman tile was discovered at Vindoland, a Roman fort near Hadian's WallSize of the bare footprint indicates it was made by a teenagerIt's the only tile found there to have a human print, despite thousands having been found near a tilery at the ancient site
