Not my experience AT ALL I am 64 I just built a 3700 sq ft. house by myself and a little help from friends and fam. I carried around 24' 8x10's 4x10's 20' high ceilings 12/12 pitch roof and I did all of it, electrical, plumbing, landscaping, roofing, framing, basement, the only thing I contracted out was the closed cell foam I did it in 2 years smoking every night to help sleep and with the pain. So there is that.
