Last month I has my 78th birthday, is there anyone here who is older than me. I can still remember snatches from the air raids in the second world war, and it is interesting how some things make such an impression on children's minds.

Obviously I have a lot of friends who are over sixty, and not many seem to be able to understand the concept of virtual assets, even when I cite the examples of stories, and fiat currencies.

Last month I has my 78th birthday, I think the right sentence is: Last month I had my 78th Birthday
