Climbing and T Shirts

Went climbing on Monday with this t-shirt on. One of the staff asked what it was from expecting something to do with a medical group as he's doing his paramedic training at the moment. This turned into a longer discussion about the benefits of metric, especially for medicine.

Something as simple as wearing a t-shirt and being willing to have a conversation about metric can make the difference between someone ignoring it and thinking about the wider impacts (and possibly even doing something about it).
