Welcome to Pianostreet! No age should limit ones interest in music.
Darren,
I'm older than you (54
) and started about four years ago. I've been at it about 45 minutes - 1 hour daily. I'm very disciplined, hardly ever skip a day and enjoy it every day. My most gratifying moments are when I for the first time get my fingers right on harmonies which reverberate through my body and soul; such beauty!!! At those moments I feel deep respect for the composer who came up with it.
I'll never be good; started waaaay too late, but enjoy every moment of it (and laugh a lot at myself in the process).
Keep at it 
Rene
The only reason you'll never be good is that if you truly believe it yourself. Having faith in the Lord above and yourself will give you the strength to play beautifully.
I havn't even played 6 months and I'm progressing at a good tempo. Like yourself I play an hour a day. Some days shorter, some days longer. Give or take.
And my age (20) is above the expiry date for normal concert pianists, so...... Don't let anyone tell you otherwise.
Honestly.....If you wanted, even at age 54, you could become whatever you desire. If you played 6 hours a day and divided the hours well with breaks and all, you could be truly magnificent in a year from now. But then you'd have to give up any obligations in real life, or not, not sure.
By 6 hours practise I do mean at least an hour of agonizing scales, lmao. (I like the scales though, makes me feel alive.)
