又再跑步，跑快一點，不過跑得太快總是有陰影會暴斃。明早看心臟科醫生，就知道我的心臟是不是衰竭，或是哪裡堵住快死了。

今天做引體向上，用了很多重量協助都不可以，左臂近一年前受傷後就做不了。去年疫情爆發前不用重量協助可拉五次，可惜了。

It seems that the Twitter post you provided does not relate to a maintenance report feedback to public flat house. The post simply contains a mention of "activesg" and "yishungym", which do not provide any context or information related to maintenance issues or public housing. Therefore, the answer is "False" for the "relatedness" field, and the "type" field is set to "none" since it is not possible to determine the type of feedback or issue being mentioned in the post. The "explanation" field is left blank since there is no additional information to provide.
