Sick.....

I can't tell you how many times I've been unwell this winter so far....I keep coming down with these colds and I have another one now that started today and has been getting worse as the day has gone on.  I think its a mixture of commuting into central London every day and also I find when I swim a lot I get colds.  I've been eating really healthily so not sure why my immune system is so low.  I think I will rest all weekend and cancel any plans so I can relax :-)
