Any time I hear someone use the so-called reasoning or argument of "it's my life and my choice and I ain't hurting nobody!", I always think of Trevor.
You're lucky if you survive unscathed. You could even say you're lucky if you die an instant death. The pain for your family would be harsh, but something like ripping off a Band-Ade....it eventually eases.
But a TBI is another matter. Your "freedom" now means someone is giving you a sponge bath or changing your catheter or wiping your ass. Helping to feed you and put on your clothes. Helping you in and out of a wheel chair or vehicle or, even worse, rolling you over to prevent bed sores.
People seem to think of it in a live/don't live scenario and never think about the gray area that Trevor is in. A life permanently changed. For him, his family, his (once) fiancé, his band mates, co workers, etc.
If you were friends with Trevor on FB, you would see him longing for the days of playing in his band. Begging for a girl...any girl....to be a surrogate so the he can have a daughter (he would name her Sacagawea, BTW). Begging for visitors and to not be forgotten. Reminiscing about Dee Dee, his CB550, and the epic road trip he took but can't really remember.
So, yeah....it's your choice. But it's an extremely selfish choice.
