Reliquiae

Think I'll pass on seeing the Relics of Mother Theresa here in St. Louis at Sts. Theresa and Bridget Catholic Church on Thursday. Curious as I am to see what might be there, according to the paper, the relics include the following: sandals, crucifix, hair and blood. I can understand the sandals and crucifix, but how does one even collect the other two? Sounds somewhat creepy to me. Who gets the job of collecting the biologicals even? Thanks for the invite, but no thanks.
