For me, it has been out of laziness that I have built up many long educational videos in youtube "watch later" list. Only recently did I notice youtube will keep track of where I left off, so I can break the logjam by watching in bits. Many are from visiting experts whose lectures I skipped after I promised myself I would watch their video.
I can't believe I am contemplating skipping a lecture by the archeologist who worked on a boat that could have fought Vespasian in a naval battle on Sea of Galilee off Mary Magdalene's home town of Migdal. Below I post an old video of his lecture (not a series but long) whose production quality isn't great, but can be supplanted by his writeup of the Roman history context http://www.jesusboat.com/jesusboat-archive/ancient-seafaring-and-the-jesus-boat
