Buy a pair of goggles to protect yourself when doing things like tree trimming.
I learned my lesson know. I have some palm trees called pygmy palms. The fronds can deliver quite a wallop, and they have thorns. I do wear gloves, but i have to find some gloves that go all the way up to the foreman. These palms have thorns! At least i have been out in the fresh air, and in the beautiful sunlight.
