…After a battle with brain cancer, and the resulting acquired brain injury (ABI) that I have to deal with on a daily basis… we’ve (well, it was all Steve really!) sussed that my brain sends the signal to breathe, but not the one to make sure my head’s above water first (!!) resulting in near drowning every 20seconds! Steve suggested I try a full face mask/snorkel … and it’s working !!! Really enjoying my swim sessions now, and seeing improvements every week!
