Are the hm wearing heart monitors on their wrists?

I also noticed they all have square "watch" things on their wrists, but have heard no mention of what they are for.

Thats what I meant!!

Yeh, I saw them as well, but then I thought it was just something trendy that I didn't know about.

But then again, I'm drunk

they have just said they ar bio-rythem monitors

Interesting................... have they said what is behind it, or are we more likely to be getting readouts on BBLB?

I heard that, is that just spin for the HMs? Given it's size it's going to be a fairly simple device, & arn't bio rythyms something to do with energy levels throughout the month.
