I am Peter Hodes, a volunteer stem courier. Since March 2012, I've done 89 trips of those , 51 have been abroad, I have 42 hours to carry stem cells（干细胞）in my little box because I've got two ice packs and that's how long they last, in all, from the time the stem cells are harvested from a donor(捐献者) to the time they can be implanted in the patient, we’ve got 72 hours at most, So I am always conscious of time.

I had one trip last year where I was caught by a hurricane in America. I picked up the stem cells in Providence, Rhode Island, and was meant to fly to Washington then back to London. But when I arrived at the check-in desk at Providence, the lady on the desk said: “Well, I’m really sorry, I’ve got some bad news for you-there are no fights from Washington.” So I took my box and put it on the desk and I said: “In this box are some stem cells that are urgently needed for a patient-please, please, you’ve got to get me back to the United Kingdom.” She just dropped everything. She arranged for a flight on a small  plane to be held for mere-routed(改道)me through Newark and got me back to the UK even earlier than originally scheduled.

For this courier job, you’re consciously aware than that box you’re got something that is potentially going to save somebody’s life.

   A young Los Angeles actor in need of a second job to pay his bills has come up with a brilliant way to supplement his income — people walking.

Chuck McCarthy originally considered becoming a dog walker to earn some extra cash, but soon realized that the job requires more than walking dogs on a leash. However, walking people doesn’t require much when they are out on walks. Chuck realized there would be money to be made if he walks people around Los Angeles instead.

It might sound like a joke, but The People Walker, as he calls himself, is very serious about his new job. For $7 per mile, he offers to walk with clients around L. A., listening to their problems or simply making conversations and offering them a sense of security. At 6 feet, 2 inches, and with a bulky figure and bushy beard, Chuck doesn’t look like the kind of guy you’d want to mess with.

Chuck’s services are aimed at people who need a motivational boost to go walking, those who don’t feel safe walking alone in some areas, and those who are afraid that people might see them walking by themselves and think that they have no friends. “I wear my The People Walker shirt upon request and on the first walk with a new client, so he can be 100% sure it’s me,” McCarthy says. However, he admits some people are a bit uncomfortable with this policy, as they don’t necessarily want everyone to know that they’re being walked.

So far, Chuck McCarthy has already had another five people walkers employed, covering various areas, like downtown L. A., Hollywood, Eagle Rock, or Fairfax County. Once he posted signs around the city, his phone started ringing and clients began rolling in. And with all the free publicity he has been getting in the press lately, more requests are coming.

While he hopes that his acting career will take off soon, Chuck is very happy with his people walking business. After all, it’s literally a walk in the park and it pays the bills.
