Oldest person to swim the North channel

I am a triple crown swimmer wanting to swim the oceans 7 challenge, of which I have already swum the English Channel and the Catalina channel. I need to raise the money as I'm unemployed and just coming up to retirement making me what would be the oldest 7 oceans swimmer as my first slot opening is the hardest of all the swims. That's the North Channel between Ireland and Scotland. Each swim I will need to crowd fund and to actually get this first slot To date, I had a very generous donor who paid my deposit, thank you so much, without sponsors this would be impossible. I have also booked the Bristol Channel in August as part of my training to wards my build up.
