Riz Ahmed Shares ‘One Last Thing’, From a Life Hack to a Time He Was Speechless (Exclusive)

From iPhone life hacks to artificial intelligence, actor Riz Ahmed, 42, who stars in the new thriller Relay, sat down with PEOPLE for its One Last Thing page in this week’s issue, on newsstands now:

Last life hack I tried
Someone showed me how you can turn your phone to gray scale; you just turn off the color so it’s black-and-white. It starts to be less like candy for your brain.

Last time I sang out loud
That’s most days. I might sing in front of people. I’m not hitting high notes and doing Beyoncé-type runs or anything, but I sing along. 

Last time I was speechless
Somebody sent me a video about artificial intelligence bots starting to communicate with each other in a secret language that none of their human designers understood. I was just like, “It’s coming.”

Last time I danced
Yesterday, here in the hotel room. I dance all the time. I think the best kind of dancing shouldn’t look good. It’s about how it makes you feel. 

Last injury
I was walking around at night, and I smashed my knee against the corner of the bed frame. I was limping the whole next day and couldn’t remember how it happened, like, “I’m just getting old.” 

Relay is now in theaters.
