There's a Small Possibility, I may Not be Indestructible

I'm a very fortunate person, insofar as having very few alignments or injuries.  I push myself to do challenging things and seem to be able to succeed at them.  I've come to joke (wth increasingly less tongue-in-cheek) that I'm indestructible with my loved ones that often are keen to see me eat better, be smarter regarding my general health and so on.  Don't read this wrong - I'm not certainly not excellent at everything I do, nor able to do incredible stuff - I'm just able to continue to succeed at those things I put my mind to physically.  

I'll admit this has certain downsides - I have little passing awareness of most things medical, as I've never really had cause to pay attention to that stuff.  I also have low levels of drug knowledge, as I don't really partake in any. But the upside has been great.

Stretch a little before-hand, and be cognizant of what's reasonably taxing, and it'll be fine.

Lately however, I experienced a small nagging injury.  It hasn't stopped me from doing what I need to do - but it has created a sense of empathy for anyone who is active, and does so while in pain. It's also brought to light that I ought to be more careful and considered when talking on challenges.  I'm going to let common sense prevail and do what feels ok.  But I fear what's really irreparably damaged is that small belief that I could do anything.  Try and find a physiotherapist for that!
