You sound like an older version of me, especially with the saying 'ace' all the time, haha.
Thing is... recently I had to share the company of a load of 17 year olds, and girl told me that the word 'ace' was quite old fashioned. I was hurt at first, but I became obsessed with this and had to find out, so I asked lots of people aged 18 and under whether or not they said 'ace', and it turns out that there are a lot more young people who say 'ace' than those who don't.
Which I thought was pretty ace...
