Same here. I've been walking our dog twice-daily for the past 2-3 weeks or so and today I have walked him 3 times.
A. Because I really care about him. B. Because I am trying to get fitter and more active myself, free of charge and in the fresh air. And of course, every little helps in the fight against this blasted virus.
As to whether I am unconcerned about CV, I most certainly am concerned, but more about the prospects of my parents catching it, as my dad is 71 (though reasonably fit and healthy with no obvious underlying health conditions), and my mom is in her late 60s, has had mild traces of asthma in the past, but now suffers from dementia and is therefore struggling to comprehend all of this CV stuff, but really indignant about not being able to go in shops, etc, which I am currently tasked with doing ATM. I'm not currently losing sleep over the thought of me catching the virus and constantly trying to follow the drill whenever I have to go into shops, etc by keeping as far apart from other customers as possible, and visiting the toilet to wash my hands (if the given shop has one intended for use by the general public, of course), and wiping down the outer packaging of all of the stuff I have purchased with anti-bacterial wipes once back home.
I don't know how I would have coped with all of this in the past (probably even ten years ago) as I have Asperger's Syndrome, and people like me are often disturbed by major changes to our existing routines but my dad told me over tea time today that he thinks I have successfully 'risen to the occasion' with all of this and have really been a godsend for the entire family. I don't in any way feel exploited either, despite my own personal issues.
I don't intend to be a smart alec and keep blowing my own trumpet but I am feeling really proud of myself so far.
