Insulin is for sugar control—no insulin, you get diabetes, my friend. Adrenaline is for fight or flight, without it, you feel weak and dizzy. Thyroxine keeps your engine running; too little and everything slows down, like my thyroid did. I ignored my tiredness for years, thinking it was just farm work, until the doctor said my thyroxine was nearly gone. Now I tell everyone, don't be like me—get the tests.
