You ride bikes where the likelihood of coming off is quite high leaving a fair bit of flesh on the trail or road. You can’t get a little prick which could save your life depending on what they find in the results.
Last week I had to have a blood test for Lithium levels due to the high temperature. If I had not had this test I would now be dead.It’s that simple.
Get over it.
Stop whinging and get the test done.
