My personal prediction for the year 2018:

In twenty years time I'll be 56, hopefully as healthy and happy as I am now, still lucky to be living with my dear partner Bruce and still working in education, although preferably training teachers rather than be one myself. 

I would be looking forward to retirement rather than fearing it - I've always had a thousand and one things I'd like to do and I can't see that changing much when I'm older.
