What does an island on the life line mean?

What this means

First confirm the island is a closed oval where the life line splits and rejoins, not a shadow, dry-skin mark or crossing crease.

Palmistry often reads life-line islands as draining periods, but a careful reading keeps the meaning symbolic and looks at the line after the island.

Compare depth, nearby support lines, breaks, the head line, heart line and both hands before making any strong claim.
