That's dangerous, you're too old to be doing it!

Just turned 53. I was doing some roofing on my house last year, my neighbor who is 65 says" you should get some help" I said ":what some young 32 year old that tells me he's roofed before then he falls and gets hurt and wants me to pay his medical bills? that kind of help..." i have to get back up there this year I didn't get to it all before winter, but this is it I think Ill be too old to get up there soon.
