European scientists have developed an artificial hand that can be hard wired into the body's nervous system, allowing touchy-feely signals to reach the brain.
Singaporean scientists are jealous. Why didn't they think of this? Installing an artificial hand in a strategic place in your home (say, your child's night table) enables parents who don't have time to come home to caress their kids and touch them reassuringly if something's wrong. Or then again, maybe that's not such a good idea.
Anyway, possibilities are endless and not only limited to replacing either body parts or Singaporean hugs. All that's needed is a little thinking out of the box.
For instance, you could even put audio sensors in the thing. Would give a whole new meaning to the increasingly popular expression 'Talk to the hand', as described in Lynne Truss's extremely entertaining book.
