I am 51 with 28 years with AT&T.....seems the chopping block comes around each year for some of us.....I had already talked to Alamance Community College about HVAC school......my sons and I were thinking that may be something we could all get into.......fortunately I am still employed......but a trade was my first thought.I'm mid-40s and considering it.
If you are 40....go for it! I think you can make a great living at any trade right now.
