Another plus one here!! Smoking is shit if you do it a lot or daily and especially bad if the first thing you do in the morning is smoke,, odd one here and there doesn't make much difference, if any, especially if you are young, but the older you get the more the die are weighted against you, best to just stop.
I am not quite 2 years having stopped smoking, so still got a ways to go it would seem... but if I ever did something just in time, that was it... I had long-* from having had a super mild case of * right before lockdown which has destroyed me and especially my lungs - feels like so much capacity lost. I am okay, running, feel better, but whether I will ever be the same again... who knows? Most of the bad symptoms have subsided, (the terrible wheezing and rapid onset muscle fatigue) but still have occasional tinnitus which I never had before, but the headaches, inexplicable aches and pains, random eruptions on my skin etc. have all gone thankfully! Counting blessings. Hope to be 100% okay again one day and if not, well that's okay too. If you get to this age then you have done better than a lot of the rest of the worlds population. Every day very young people die, more and more it seems at the moment. Count blessings. They are taken away so easily.
Last run, which felt good, was 5.62 miles, 1:16:35, avg pace 13:35 min/mi, 728ft elevation climb - this is over the moors so contending with boggy ground, loose stone, patches of ice, etc. so not great, but not entirely terrible either!
