That is my thinking. I enjoyed a 22 miler today.....have cycled 96 this week as well as 2 decent walks and am feeling good (for an old git).....so hoping they can sort it out.Well, look on the bright side, if you've been walking around with a chronic blockage for two years, think how fab and full of beans you're going to feel when they've flushed it out - Like a new man!
