All the best, many people in their middle or late aged lives with family and established UK based careers will look at what you are doing and be very jealous. It is unlikely you will get the chance to see the world at your leisure at any other time in your life after about age 30, so lap it up and make the most of it!! Have fun but be safe!
No doubt with modern technology, despite travelling the world, we wont even notice you are gone in this medium!
