I beg to differ. Calling going out to a gym, cafe, club or a bar during wartime, as anything other than enjoying life, diminishes the real tragedy of those who are fighting on the front line and don't enjoy such leisure activities. Some people are fortunate enough that they can still get to enjoy life even if their country is in a war, as just like in every war ever, not everyone is affected equally.
I agree. However if we talk about Kyiv, I'd like to remind you that electricity is available 2-4 hours per day, in some regions there has been no water nor heating for the last week.
Everyone I know are extremely stressed, and if anyone visits their gym, it's not to enjoy life, but to not slip into total despair.
And "enjoying their daily lives" diminishes real tragedies of Ukrainians' daily lives.
