There’s only two weeks left of this infernal imposter summer. Make the most of it by doing something that gets your adrenaline pumping. Ride a rollercoaster.

I had forgotten what a rush it is to hurl down a clickety clack track at 50 mph but the fear and exhilaration came racing back to me recently when we attacked the 12 rollercoasters at Hershey Park, Pennsylvania. I only rode about four of them before my stomach gave out, but thrillseekers Dave and Clare squeezed in as many as possible before the park closed.

Boredom and routine can cast a shadow over the joys of everyday life. It’s a rare day when we do something so exhilarating it gets our adrenaline pumping and we lose all inhibition. That’s what’s so great about rollercoasters. You don’t worry about what your hair looks like, or about that deadline at work. All you can think about is what’s around the next bend. I don’t think at all. I literally scream the entire way around the track at the top of my lungs. I can’t think of a greater stress buster in the world.

This week’s #HappyAct is to ride a rollercoaster. Let every inhibition hurl out of you and feel the thrill of the rush. The Canadian National Exhibition is on in Toronto. Relive your youth, spend the day at the Ex, and scream til your lungs hurt. Leave a comment—what’s your favourite rollercoaster?
