My 55 year old dad is a security guard making $12/h, I feel guilty

I am 20 years old with a pretty decent well paying job, and although I don't do a lot of the shopping for them I do support them financially, although my dad doesn't know, my mom does, as he would get angry if he did.<br><br>Today I am happy that my dad is still working, but my mom told me about what happened to him. When he was walking home he slipped and fell on a patch of ice, and even though he's fine, I just felt terrible that he's still working this hard in these kinds of conditions. I deal with the same thing walking to work, but it's not as bad for me since I don't have to walk for almost an hour to get home like he does.<br><br>I feel guilty because despite his age he's still putting in 40+ hr weeks, and I want to give him a better life, he's the only parent I have and I don't want to lose him to anything like an accident like what happened. I may be paying off debt, and not making much, but I can still use some of my savings. <br><br>I also want to tell him, but I don't know how as he'll probably end up telling me something like "I've been like this for years, I still have a job, I can take care of myself" and he'll just get angry at me, but I want to let him know that I do want to take care of him too, as he's sacrificed so much for me when I was younger.
