I think this study corroborates what you are saying http://jama.jamanetwork.com/article.aspx?articleid=200731

Results Relative to the normal weight category (BMI 18.5 to <25), obesity (BMI ?30) was associated with 111 909 excess deaths (95% confidence interval [CI], 53 754-170 064) and underweight with 33 746 excess deaths (95% CI, 15 726-51 766). Overweight was not associated with excess mortality (?86 094 deaths; 95% CI, ?161 223 to ?10 966). The relative risks of mortality associated with obesity were lower in NHANES II and NHANES III than in NHANES I.

Mine starts with a 1. 20+ would be unhealthy for my body type but everyone is different. Just focus on healthy eating and movement.

Yes, here's a good link (including limitations of this metric):

BMI of 30+ is considered obese.

Specifically, I just read somewhere that you should shoot for a BMI that starts with 2...so 29 is ok. It went on to say that BMI in the 30s is when you start to see morbidity and mortality issues..
Has anyone heard this before?
It's making me jumpstart my weight loss regimen as I need to lose 20 lbs to get to 29 BMI. That seems more doable to me...
