Now I find that perspective gets more difficult to judge properly as my astigmatism gets worse as I age. (Straight lines in architechure are no longer straight to my eyes.)
A little more seriously - I find myself being a lot less adventuresome even road riding. Now that "what if" seems very real. For one thing, I may well have done it already. For another, I will almost certainly be stacking this new injury on top of an old one and that is getting less fun.
