I'm a vagabond of sorts, jack of all trades
I think one can get insurance for anything. All types of insurance policies can have exclusions and limits. I happened to get a good policy, my only exclusion is disability for being MENTAL. BUT every company is different as to premiums length of beni's, and exclusions. If you suffer disability b/c of excluded activity you're hosed. Read the fine print!
As for debt, getting disabled in the 10 years after training with substantial debt, you are once again hosed.I think disability in the face of substantial debt is not on the radar screen of most recently graduated professionals (MD, JD, MBA, etc). One is too proccupied with work, feeding kids, etc. When young we never think about needing life or disability insurance It's a real gamble. I guess be frugal, have your spouse work, and keep debt down. But I went to a state school where tuition was $1600 a year instead of $20000+ at say Wake Forest (1988 dollars)
Funny thing is I almost cancelled my health plan 3 months before my accident. I'm glad I didn't, bills were about $35k (1991 $)
Insurance, we all bitch about it but when we need it it comes in handy. I hate to sound like an add for "the ones who collect $ but hate giving it away" but life is risky. I do too much "foolish" (as my mother says; "You have a femily to take care of!") stuff but ones needs to think about these things because a bad disability will cripple your family. Plus bro's, who sell me my insurance, told me to say this. Thats why they belong to the country club and I don't (though I'm not much on that anyway).
BTW Travelers sucks
