My wife and me are both over 70, have health problems, and up until last week I was a smoker, so very vulnerable. We have been isolating since 12th March, all food and booze is delivered. The main problem is boredom, and that "caged" feeling.
For me, it was a great thing to sit outside and have a smoke, god I miss my Cigars ! it passed the time, and relaxed me, but, I know it made me more vulnerable, so had to stop.
I walk daily, and always meet some nice people, stay 6 feet apart, and have a chat, so it isn't too bad, just miss days out by the Sea, eating in Restaurants, drinking in Pubs, and....... my Cigars !
Really though, I am grateful that it is all not too painful at all, the only thing that makes me ache, is not being able to see and cuddle my grand kids, but even that will come back.
