My teenage grandaughter is in class where she is studying to get her RN license. My daughter is 41 yrs old so I guess that doesn’t count.
Good for your granddaughter! One of my church friends has a daughter who got her CNA license the summer after her junior year of high school, and already has a scholarship/internship lined up for nursing school.
There is a great deal of ground between sitting around doing nothing, and doing something foolishly dangerous that, even if completed safely, would not really add any value to the world.
