history: my co worker took out his back I remember the one time my co worker took out his back _comma_ he would still come in to work but i made sure i did all the heavy lifting so he wont he eventually got better That is some dedication.  Did he finally heal up?
current: took him weeks , but i just felt bad i worked with him for years 
next: I'm glad to hear that he is better now - you did a great thing by helping him.
