Does BMI apply to athletes?

Not well. Muscular people can have a high BMI without excess body fat.

Do the ranges differ for older adults?

Some guidance suggests a slightly higher range can be healthy in older age. Ask your doctor.

Is being in range a guarantee of good health?

No. Diet, activity, and other health measures matter too.
