Hi,
I was recently in a similar situation to you - I applied for NATS in the UK at the ripe old age of 30, and by the time I had completed the application process ( I took my time as I reckoned it was my last chance) I was almost 32 by the time I started at the college. Passed the Aerodrome course 8 days after my 32nd birthday and validated before I was 33.
What the above rambling is trying to say is that, if you have the will and tenacity to take on all the inconvieninces that starting training brings with it: relocation, tiny salary (by most 30 year-old's standards) and a whole heap of hard work then age is no barrier and at the end of it you get one of the best jobs in the world.
I know that NATS had their age limits challenged under equal opportunities legislation. How Eurocontrol and other ANSPs continue to get away with it is beyond me.
If you want any further info specific to being an old codger (because you will feel a bit like that during training) then drop me a PM.
