I've never had major issues with my weight, the most I've weighed was 150lbs.
I'm in the 26-32 age range and 5'6" height or 168cm.
I'm active and like to stay that way because my eating habits were once very unhealthy and making me sick.
I'm also vegetarian and have been so since my 20's.
Lately however, I've heard people saying how skinny (115-120lbs) I am and that I need to gain weight. I wonder to myself, do I really need to gain weight just to satisfy someone's perception of what 'healthy' is or perhaps I am healthy because I FEEL healthy?
