Arthritis is inflammation of the joints (the points where bones meet) in one or more areas of the body. There are more than 100 different types of arthritis, all of which have different causes and treatment methods. The symptoms of arthritis usually appear gradually but they may also occur suddenly.Arthritis is most commonly seen in adults over the age of 65 but it can also develop in children and teens.steoarthritis, one of the most common forms of arthritis, is caused by normal wear and tear throughout life; this natural breakdown of cartilage tissue can be exacerbated by an infection or injury to the joints. The risk of developing osteoarthritis may be higher if you have a family history of the disease.
1 If you send your invitations out 6 to 8 weeks in advance, the likelihood is that most of them will come. 2  So estimate that 85% of them will attend. 3  Donât forget to account for plus ones, if youâve invited them.4  Out of town acceptance rate is around 85% for family and 40% for friends. (# of out of town guests * 65%) + (# of local guests * 90%) = total # estimated to attend. 2  Itâs a good idea to make an A list and a B list. 3  Send your a list invitations out 8 weeks in advance. 4  As you start to get acceptances and declines, you can start inviting some of the people from your B list.
If you plan to send additional invitations as you receive no RSVPs, count back an additional two weeks to set your mailing date, so that guests whose invitations are sent later still have plenty of time to reply. Nothing says ââB-list guestâ like receiving an invitation at the last minute.
