Dear June,

Please accept our apologies for the late reply to this thread, I appreciate that it has been a very long time since you posted your question.

My name's Peter, and I'm now with Multisensory Playsafe (MSPS) and am tasked with, firstly, apologising for the late reply to this email, and secondly to actually deal with your request!

The answer to your question is a simple No, there is no age limit to Johns designs and applications.
