Almost certainly - need to be careful though since there tend to be more than a few teachers on these forums!
Was giving this some thought. No-one older seems that surprised but I was thinking when I was 30ish what I remember and maybe it's only once we get older we realise what we are capable of. Since I've always run to verying degrees it's still natural to do it. I think it's quite something when someone decides to do it for the first time later in life, but then again until they try it how do they know what they can do. Perhaps it stops us putting limitations on ourselves?
