Hey All.... I have a close ISFJ Male friend who constantly frets over gaining a pound (weighs himself daily) and dyes his hair except for two gray streaks around his temples. His appears to all who know him to obsess over his appearance and be vain in general. He is very trim already so an extra pound seems like a very girly complaint in my opinion. He seems so hung up on himself for an ISFJ. What do you make of this? Is this normal for ISFJ men? I thought SJ's were not supposed to be so self-involved.
