Write a sentimental and creative poem, and put it in a picture frame. If you aren't much of a poet, you could always choose a nice poem from the Internet.
Family portrait on canvas
This can be a good gift from all the family members. Turning your best family photo into canvas art will surely put a smile on his face. Another option would be to make a collage with the best family photos or with pictures of him from when he was a kid. This will be perfect to hang in his bedroom.
You could also give him chocolates and flowers, and play his favorite music for dinner. This will be a birthday that he will remember for the rest of his life.
Massaging bed rest
A massaging bed rest to help relieve sores and muscle fatigue is a present he can use for a long time. Choose one with a high-speed pulsating massage to make him feel relaxed at home.
Get one of his favorite cuisine. If he orders in a lot of Chinese food, a Chinese cookbook would let him have his favorite food whenever he wanted without having to get takeout.
You can always make homemade gifts, maybe something like a birthday card or hand painted ceramic mug. You could write a letter to him, it'll be a welcome change from emails.
