suppose, I played football in my childhood. in 2016, I am sharing my that experience with my friends like this way
I have played football but I have not been able to play since I have been affected by arthritis.
my explanation: I have played football- I am sharing my experience without mentioning time. therefore I use present perfect. I have not been able to play - I cannot remember when I have stopped playing and I am still not able to play. therefore that past event is related with my present situatuion. hence I use present perfect. since I have been affected by arthritice- I still have arthrice and I don't know the time when I have been affected.
please help me to understand whether I am using right tenses to express a past event.
