Absolutely! As others have pointed out, there are ways to access those funds without penalty prior to "traditional" retirement ages. You need to read up on this, because if you're not using these accounts to your maximum benefit, you may be overpaying in taxes as you save.
I don't, however, count my pension funds, even though I could withdraw them as a lump sum (with interest), I am pretty sure I will keep the funds in the pension and draw a monthly amount starting at 55 or whatever makes sense at that point.
