Simple vocal tics consist of sounds that do not form words, such as: throat clearing, grunting, coughing, and sniffing. The DSM-IV divide tic disorders in three main categories: transient tic disorders, chronic motor or vocal tic disorder and Tourette disorder.
If you are healthy person who has been exercising regularly, after you donated blood, you wonder whether you can exercise right after that. The answer is no. You should only exercise after at least 5 hours of resting. Do not run, swim, do weight training or other rough movements during the first 5 hours of donation. In fact, even after that period, your competitive performance in the court or track may be affected.
During a blood donation, a needle is used to collect 470ml (just under one pint) of your blood. You will need to rest for a short while after a donation, and refreshments will be offered to stop you feeling faint or dizzy. It is usually recommended that men allow 12 weeks and women 16 weeks between donations.
