Doesn't matter much what paddock one is looking at .. characteristic management by the old bull is tied to heuristic behaviour while that for the young bull is characterised by testosterone-fuelled risk taking, partly due to the genetics and partly due to blissful ignorance and the Darwin Principle's not having caught up with the particular individual ...
Trick for the expert is to merge that characteristic with a semblance of conservatism .. ie the sage admonition "first, sit on your hands for a bit".
We can all get bitten if we let our guard down ... for instance, I just (inadvertently because I wasn't thinking and being alert enough) closed this window and lost my first cut at this post.
Penalty = having to do it over. No big deal.
We rely heavily on experience teaching us when we can be a bit relaxed (because the consequences aren't earth shattering) and when we could get bitten badly so we had better get it right first time.
