I left my job with the nhs last july after getting thoroughly peed off with everything. i have set up my own business gardening and doing odd jobs, as a woman i get lots of older ladies on their own calling me. i must say i am fitter, happier, tho not as well off. but i would never go back to 9-5. i pick n choose my hols, can be home for the kids and have lost a few inches round the waist line being so active.
Do it!!!! if it doesn't work at least you know that you tried, good luck x
