Periodically. I have these urges that wash over me where I think: "Hey, just get out & do something!" I'm pushing 70 years old. But, hey, I'm not dead yet! I could take some classes... may be even pursue an advanced degree! (I wouldn't be the only older person to have done so.) But then I think about all of the money I'd spend, plus the fact that I wouldn't likely do anything with it even if I was able to finish... oh... & then there's the fact that I rarely ever leave the house... so then I just go back to sleep...
