Do something that scares you. Check out the indoor rock climbing center, or book an instructor to take you outside on the real thing. How about a trapeze class? Are there any ziplines in your area? A racecar driving course would be speedy fun. Get that adrenaline pumping through your veins and forget about anyone else for a bit.
