Only conditionally senior

I have just renewed my Senior Railcard online.

It will expire tomorrow, but I chose to renew rather than starting afresh, because I thought it would be simpler. After all, I've already established that I'm eligible, haven't I?

No, apparently not. I still have to give details of my passport (or driving license, which in my case I have not got), to prove my age.

After all, you never know: I might have been getting younger.
