Not everyone considers this life to be doing nothing! A lot of people love being at home, love pottering about, work at home happily, love being out in nature, hate pubs and shopping. A lot of people are quietly having a full and rich life, and appreciate how lucky they are to be happy this way.
can't take the kids swimming
can't do ANY sport, even outdoor ones are currently shut
can't go on holiday
can't go travelling
can't even go out for the day at the weekend
can't see friends
can't see family
can't have sleepovers, or friends for diner
can't go to the restaurant
can't have a birthday party
I could go on and on...
I shop just as much as ever, it's all online anyway.
I am mid-40s, I have young kids. There's only so much "pottering around" I could do without going crazy. It's not a life. Being stuck in my house is not fulfilling, the world is too big a place for that.
So I have no issue and sympathise with people like the OP who have a positive lockdown, why not, but posters complaining they are bored about people complaining about the lockdown... let's not push it.
