In reply to Rigid Raider:
Not so.
If we look back though history, long before mountaineering was done as a recreation, (and even before you started yours!), people used sticks, poles or crooks for support, aid and other such benefits. Technology has simply made it lighter, more robust (eg tips), and science has shown that as we live longer, and expect to be able to perform much later than we did in previous generations, we should/can protect/assist our joints to further this.
You may be still fit and strong, and doing what you did at 25, but I am struggling, and find my poles a real boon for all the reasons above.
To the OP, when I take groups out and the non-pole users who have given up on them make the observation, I always ask how long they perservered with them? Like all equipment, it takes a bit of practice to become accustomed to them, but once you do, you'll never feel happy without them.
