Still not well

Having a head cold i now have a bad chest infection and been signed off another week, i feel so frustrated that i can't not only start exercising i can't do basic stuff around the house and garden, i have been laid up indoors for over a week now and it really is getting to me. What worries me more is if this a sign of things to come as i get older, is it going to take so long to recover the older i get.
