Is it possible that a little fear could actually be good for our systems? I was an adrenaline junkie in my youth and still seek out opportunities to get that rush these days although it's getting harder to do while in lockdown. I have done it but you don't need to jump out of a perfectly good airplane to get a thrill. There are ways to jumpstart your body with an adrenaline rush if you're creative. My advice is to always push past your fear so you can live your best life.
