The others are right keep active for as long as you can it will only benefit you with this condition I was dx in June 2013 age 47. Also take your meds on time each day. Some of us sort of go through a grieving process life pre PD and life after dx with PD this can creep up all of a sudden so if you start to feel down please get straight to your Dr's depression is common among pwp you have to nip it in the bud before it can take hold I don't wish to scare you but you need to cover all the bases. And make sure they review your med's at least 6 monthly.
Any worries any of us on the forum will be happy to help.
