Watching the Super Bowl? Got an Apple Watch? We want to talk to you.

Die-hard Eagles fans bleed green.

What about the bandwagon fans? Or the people who don’t really care but are just in it to support the city, or because all their friends are?

Let’s do a little experiment to find out.

If you’re watching the Super Bowl in the Philadelphia region and you have an Apple Watch, we want to talk to you for a fun little experiment looking at your heart rate.

Not just the super fans, either — we want a mix of people.

How much faster does your heart start beating on Sunday as the coin toss approaches?

Will the loyalest fans have bigger heart rate spikes than the bandwagoners?

When will your heart rate rise the most — when you’re celebrating an incredible Eagles play, or when you’re freaking out over a Chiefs one?

So here’s how we’ll do this: We’re looking for volunteers to send us their heart rate data the day after the Super Bowl and then talk to us about their experience of the game. Fill out the form below.

If it seems like you’re a good fit, we’ll be in touch, and we’ll make things super easy for you. We’ll walk you through sending us the data step by step, followed by a short conversation to talk about the big day.

Oh, and we’ll only be looking at heart rate — none of your other data will get used or published in any way.
