I had a physically active lifestyle & was working on my thesis before I got "mild" #covid.
About 10-20% of people get long-term symptoms after COVID. Being healthy and/or vaccinated does not protect you.
Please protect yourself & others from getting infected in the first place.
@meganeko similar here. I worked 40h manual labour and could swim 50 laps before, now I spend all my days sitting or in bed; a 1km walk takes an hour and is a day-filling exercise.
