I have read that the ideal weight for a girl 5’ tall is 100 pounds. Then you should add 5 pounds for every inch over.
At that rate she was about 20 pounds too skinny.
*shudder* I'm 60 inches high and that would be about 10 pounds more than is welcome anywhere on me.
Heart attack at 20 sounds like an undiagnosed heart condition rather than drugs or bulimia.
