general::
Also, in the flesh. In one's physical presence, as in He applied for the job in person, or I couldn't believe it, but there she was, in the flesh. The first expression dates from the mid-1500s. The variant, from the 1300s, was long used to allude to the bodily resurrection of Jesus, but later acquired its looser meaning. Charles Dickens has it in Our Mutual Friend (1865): "The minutes passing on, and no Mrs. W. in the flesh appearing."
