I've had over 6 years of practice of not doing a lot* since I broke my leg so it hasn't been much different, I pretty much stopped going to pubs since the smoking ban as well. I do miss mates coming round but the new BT package we're on gives us unlimited phone calls at any time even to mobiles so staying in touch isn't a problem.
* I can still do things but only for an hour or so before the pain gets too bad and I have to stop and rest.
Due to health issues in the family we have been practicing disappointment in not being able to do things we had planned to do for some time. Also being a less-than-interesting person with a line in really not funny jokes, we have also been practicing social distancing too, although unintentially. So at the moment I feel like my life has been one long training session for this period.
Latest lockdown skills involve determining the differences between a 7-year-old boy and a 6-year-old boy. I would have thought they would be rather similar, or at least easy to extrapolate from one to another, but this is not so. Probably a good idea to start thinking about the psychology of an 8-year-old boy now, rather than later.
I have also been out running with him. We did 5k today. 30:30. Starting to extrapolate his times, and he may well beat me before he hits his teens. That's only 6 more years of being able to talk to him whilst running.
